“…In the case of 2-dimensional metal-ion amino acids frameworks, a typical µ2-O1:O2 coordination mode can be obtained with glycine (Gly) and Ni II (Table 1, entry 1), [69] Mn II , [70] and Co II . [71] Two amino acid ligands can coordination through an O,N-chelation mode with a metal ion that allows octahedral coordination. However, by using the second oxygen atom of the amino acids carboxylate, bridging to a neighboring metal ions can occur through a µ2-N1O1:O2 coordination mode.…”

Metal organic frameworks (MOFs) are extended structures composed of a network of organic ligands and metal ions or clusters connected to each other via coordination bonds. The numerous choices of organic ligands and metal coordination geometries have led to the construction of porous MOFs with various compositions, network topologies, pore sizes and shapes and they possess high surface areas and low densities. The structures of MOFs can be tailor-tuned in such a way that any desired ligand or/and metal ion can be incorporated; this has given to researchers the advantage of designing MOFs for a targeted application. Within this review, we overview recent examples of a sub-class of MOFs namely biologically derived MOFs (bio-MOFs), made of multifunctional and commercially available biologically derived ligands (bio-ligands) such as: amino acids, peptides, nucleobases and saccharides and focus on their coordination chemistry with a variety of metals. Central to this review are four tables detailing the coordination modes of bio-ligands to metals, along with a visual representation of the bio-MOF that is subsequently formed. Through the detail analysis of these structures, we highlight the structural impact of these ligands on the structure, and their contribution to the MOFs properties and applications. Finally, we showcase the potential of bio-MOFs in several research areas such as CO2 capture, separation, catalysis, drug delivery and sensing.

“…The inherent polarity of the betaine and the zwitterionic glycine molecule seems to be a useful prerequisite for the synthesis of new non-centrosymmetric or even polar crystals. As a part of our studies on compounds of glycine with inorganic metal halogenides [4][5][6][7] we have investigated the system glycine -ZnCl 2 -H 2 O in the temperature range between 20°C and 70°C. These studies corroborated the existence of three compounds, namely glycine zinc chloride hydrate NH 3 CH 2 COO ⋅ ZnCl 2 ⋅ H 2 O, bis(glycine) zinc chloride dihydrate (NH 3 CH 2 COO) 2 ⋅ ZnCl 2 ⋅ 2 H 2 O and tris(glycine) zinc chloride (NH 3 CH 2 COO) 3 ⋅ ZnCl 2 , that was already described earlier by [8][9][10][11].…”

Large single crystals of the polar (point group mm2) compound tris(glycine) zinc chloride, (NH 3 CH 2 COO) 3 ⋅ ZnCl 2 , were grown from aqueous solutions. The refractive indices were measured in the wavelength region from 365 nm to 1083 nm and an unpolarised absorption spectrum was recorded (transparency range from 260 to 1550nm). The phase matching conditions for second harmonic generation were analysed: both, type I (ss-f) and type II (sf-f) are possible in the red and near IR region. All five components of the piezoelectric tensor [d ijk ] were determined; the maximum values of longitudinal and transverse piezoelectric effects are less than one half of d 111 of α-quartz. In addition, a redetermination of the crystal structure (including location of H atoms) is presented.

Glycine / Metal halogenids / Crystal structure / Comparison / ConnectivityAbstract. The large family of glycine halogenides and metal halogenides encompasses a high variety of different crystal structures. The role of the glycine molecule as a structural unit as a mono-, bi-or tridentate ligand, of the halogenide ions as well as the composition and condensation of the cationic polyhedra is discussed. With respect to the connectivity of the building units, five different structure families of glycine halogenides and glycine-metal halogenides can be distinguished. Parameters such as symmetry, ionic radii, electronegativity of cation and anion and their difference, charge, coordination number, hydration states, stoichiometric ratios and connectivity were weighed against each other in order to see if any correlations exist. The data suggest that cations with high electronegativities seem to promote formation of structures with a low grade of connectivity, i.e., isolated units, and vice versa.
