Source of materialThe mixture of Co(OAc) 4. · . H 2 O( 124 mg, 0.5 mmol) and (3-carboxyphenyl)sulfonyl]glycine (132 mg, 0.5 mmol) was stirred into 15 mL aqueous solution, which was refluxed about 1h.Then the pH was adjusted to 6orsowith 1Msolution of NaOH. The reaction mixture was heated on awater bath for 12 hat60°C, and then filtered. The red crystals were separated from the mother liquor by slow evaporation at room temperature after 1week. Experimental detailsAll hydrogen atoms were first found in the difference electron density maps, and then placed in the calculated positions. In order to obtain reasonable bond length and U eq ,the hydrogen atom attached to N1 were found from difference Fourier maps and refined freely. The remaining Hatoms were refined by riding model with Ueq(H) =1.2 U eq (C). DiscussionInorganic-organic hybrids have developed into an important class in the family of porous materials. This is due to their interesting magnetic or optical properties, their potential application in the fields of gas and liquid separation and storage, their catalysis, as well as their drug delivery [1][2][3][4][5][6][7]. Although many efforts have been devoted to the preparation of specific frameworks including one-, two-and three-dimensional structures, the preparation of the MOFs under rational control is still of great challenge. Amino acid is the fundamental structure unit of biomacromolecules, such as protein and enzyme, and it is also the important biomicromolecular ligand inside the life body. In recent years, the investigation of mixed-ligand complexes of transitional metal ions with N-protected amino acids has attracted considerable interest. The asymmetric unit of the title crystal structure consists of two 4,4-bipyridine molecules, one (3-carboxyphenyl)sulfonyl]-glycinate anion, three coordinating water molecules and one free water molecule. The coordinating (3-carboxyphenyl)sulfonyl]-glycinate anion acts as amono-dentate ligand. The Co ion is sixcoordinated (CoN 2 O 4 ), and the coordination polyhedron can be described as an distorted octahedron. The equatorial plane is formed by O1, O7, O8 and O9 from one (3-carboxyphenyl)-sulfonyl]glycine anion and three water molecules. The Co-O bond lengths are in the range of 2.095(2) -2.142(2) Å.The axial position is occupied by two Na toms from two 4,4-bipyridine molecules. The axial distance Co1-N2 and Co1-N4 are 2.230(2) Å and 2.241(2) Å,respectively. The Co-Oand Co-N bond lengths are close to those found in cobalt(II) complexes of N-protected amino acids and bipyridine ligands. Multiple hydrogen bonds are known to cooperatively exert influence on the control of molecular self assembly in chemical and biological systems. Several kinds of hydrogen bonding are observed in the crystal structure: (a) hydrogen bonding between coordinated water oxygen atoms and uncoordinated oxygen atoms of glycine anion motif (O7−H2W···O2 with the bond distance of 2.635(2) Å and bond angle of 172.5°); (b) hydrogen bonding between coordinated water oxygen atoms and uncoordinated...

Cyanoaurate complexes are a wide class of compounds with diverse structures. In particular, coordination polymers based on them have many potential practical applications, including such fields as microelectronics, nanotechnology, materials science, and medicine. In addition, when new functional materials are developed, considerable attention is paid to the possibility of participation of molecules and other structural units in non-covalent interactions, which play an important role in determining the physicochemical properties, as well as the biological activity of these materials. Thus, the presence of aurophilic contacts or halogen-halogen bonds in cyanoaurate complexes only fuels the researchers' interest in this class of compounds. Nowadays, the chemistry of gold cyanides continues to develop rapidly, so synthesis and study of new cyanoaurate compounds, as well as systematization of the acquired knowledge, remain important objectives. The present review, which includes the description of modern advances in the field of synthesis methods, study of structural features and possibility of practical use of metal di , tetra- and dihalodicyanoaurates of molecular and ionic types, is based on an analysis of the literature sources, most of which were published before 2022. Some later works are also mentioned in the review. The information presented in the article is of a fundamental nature and is undoubtedly important for specialists in the field of inorganic and organometallic chemistry of gold. The bibliography consists of 232 references.

Source of material DiscussionThe rational design and synthesis of new extended supramolecular networks are of great interest and have brought forth diversities of frameworks with fascinating structural motifs [1][2][3][4][5]. In general, the metallosupramolecular systems may display avariety of useful physicochemical properties and thus potential applications in the scopes of catalysis, molecular recognition, etc. So far many infinite 1D, 2D and 3D supramolecular frameworks have accomplished. Their primary structural motifs are dominated by metal-ligand coordinative bonds, and in this context, the design of suitable organic ligands is of the most importance. Beyond the robust metal-ligand coordination, other non-covalent bonding forces have also been proven to be powerful tools for the fine-tuning of functional architectures [6][7][8][9]. These weak secondary interactions, such as hydrogen bonds, π-π stacking and van der Waals forces, make the molecular assembly reversible and variable, and provide synthetic flexibility and functional diversity. On the other hand, the metal carboxylates have been shown to be an important family of MOFs, and have continuously received great attention for decades due to their excellent coordination capability and the possibility to synthesize new functional materials [10][11][12][13][14][15][16]. Compared to other carboxylate ligands, 4-(sulfonyl-glycine)benzoic acid does not only contain two bridging carboxylate moieties but possess another two potential groups, i. e., the nitrogen atoms and oxygen atoms of sulfonate. This asymmetric geometry may produce unique structural motifs with beautiful aesthetics and useful functional properties. It can act not only as ahydrogen bond acceptor but also as ahydrogen bond donor, depending upon the degree of deprotonation. The title crystal structure comprises a[Mn(bipy) (H 2 O) 4 ] 2+ cation and a HL 2-dianion in an asymmetric unit. The Mn(II) ion is six-Z. Kristallogr.
