“…The construction of inorganic coordination polymeric complexes has developed rapidly in recent years, owing to their interesting molecular topologies and crystal packing motifs [1][2][3][4][5] along with potential applications as functional materials [6][7][8][9]. As compared to the d-block transition metal polymers, lanthanide polymeric complexes are less common, because the high coordination numbers of lanthanide ions may cause difficulty in controlling the synthetic reactions and thereby the structures of the products [10].…”

The complexes of rare earth elements with 2,3-naphthalenedicarboxylic acid of the formula: Ln 2 (C 12 H 6 O 4 ) 3 ÁnH 2 O, where Ln = La(III)-Lu(III) and Y(III); n = 3 for La(III), Ce(III); n = 6 for Pr(III)-Yb(III) and Y(III) and n = 5 for Lu(III) have been synthesized and characterized by elemental analysis, IR spectroscopy, thermal analysis (TG, DTG, DTA and TG-FTIR) and X-ray analysis. They are sparingly soluble in water and stable at room temperature. During heating in air atmosphere, they lose all water molecules in several steps, generally in two or three steps, except for the La(III) and Ce(III) complexes which lose all water molecules in one step. The anhydrous compounds are stable up to about 773 K and then decompose to corresponding oxides. The thermal decomposition is connected with the release of water molecules (443 K), carbon dioxide (713 K) and hydrocarbons.

“…It is well known that modes of DNA non-covalent interaction with metal complexes include electrostatic effect, groove binding and intercalation; and effectiveness mainly depends on the mode and affinity of the binding between the complexes and DNA [8,9]. Along this line, many of transition metal complexes have been synthesized and their interactions with DNA studied [10][11][12][13][14][15][16][17][18][19].…”

A new one-dimensional copper(II) polymer with formula of [Cu 2 (heae)(tpa)] n ÁnH 2 O, where heae 2-and tpa 2-stand for the dianions of N,N 0 -bis(N-hydroxyethylaminoethyl)oxamide and terephthalic acid, respectively, has been synthesized and characterized by elemental analysis, conductivity measurement, IR and electronic spectral studies, and single-crystal X-ray diffraction. The crystal structure consists of a one-dimensional copper(II) coordination polymeric chain constructed by the [Cu 2 (heae)] 2? cations as the inorganic second building units (SBUs) and the tpa 2-anions as linkers. The CuÁÁÁCu separations through the bridges of heae 2-and tpa 2-are 5.2472(6) and 10.9677(8) Å , respectively. Both the copper(II) ions have square pyramidal coordination geometries. A three-dimensional hydrogen bonding network is observed in the crystal. The measured molar conductivity suggests that the polymer may stay intact in solution as the 1D polymer in the crystal. The cytotoxicities of the polymeric copper(II) complex were tested by Sulforhodamine B (SRB) assays against human hepatocellular carcinoma cell SMMC-7721 and human lung adenocarcinoma cell A549. The polymer exhibits potent cytotoxic effects against the two cell lines. The binding properties of the copper(II) polymer with herring sperm DNA (HS-DNA) have been investigated by using UV absorption and fluorescence spectra and electrochemical techniques and viscosity. The results show that the copper(II) polymer interacts with HS-DNA in the mode of intercalation with the intrinsic binding constant of 1.07 9 10 4 M -1 .

“…A tenet of crystal engineering, which belongs to supramolecular chemistry as well, is to control multidimensional network topologies in crystals constructed from molecular building blocks that are connected by means of mutual interactions of H-bonds and metal-coordination bonds [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. For example, three-dimensional (3-D) molecular networks such as complicated (10,3)-a and (10,3)-b nets in crystals can also be produced in the field of crystal engineering by a rational design of artificial molecular building blocks [27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43].…”

Anionic tris (biimidazolate) nickelate (II) ([Ni(Hbim) 3 ] − ), which is a hydrogen-bonding (H-bonding) molecular building block, undergoes self-organization into honeycomb-sheet superstructures connected by complementary intermolecular H-bonds. The crystal obtained from the stacking of these sheets is assembled into channel frameworks, approximately 2 nm wide, that clathrate two cationic K + -crown ether derivatives organised into one-dimensional (1D) double-columnar arrays. In this study, we have shown that all five cationic guest-included crystals form nanochannel structures that clathrate the 1-D double-columnar arrays of one of the four types of K + -crown ether derivatives, one of which induces a polymorph. This is accomplished by adaptably fitting two types of anionic [Ni(Hbim) − can assemble large cations such as K + crown-ether derivatives into double-columnar arrays by highly recognizing flexible H-bonding arrangements with two host networks of ΔΛ-ΔΛ-ΔΛ · · · and ΔΔΔ-ΛΛΛ · · · .
