Synthesis and structure of a novel three-dimensional coordination polymer [Cd3(μ3-hmt)2(μ2-C4H2O4)2(H2O)6]SO4·4H2O with (3,4) connected topological motifs (hmt=hexamethylenetetramine)

Synthetic, spectral, structural and catalytic activity of infinite 3-D and 2-D copper(ii) coordination polymers for substrate size-dependent catalysis for CO2 conversion

Two copper(ii) coordination polymers have been synthesized and used as substrate size-dependent catalyst for CO₂ cycloaddition with epoxides.

Synthesis, crystal structure and luminescent properties of one coordination polymer of cadmium(II) with mixed thiocyanate and hexamethylenetetramine ligands

A novel Cd(II) coordination polymer [Cd(SCN)(2)(hmt)(1/2)(H(2)O)](2).H(2)O (hmt=hexamethylenetetramine) has been synthesized and characterized by IR, elemental analysis, TG technique and X-ray crystallography. Cd(II) atom has an distorted octahedral environment with an N(3)S(2)O donor set. Every six Cd(II) centers are linked by hmt and thiocyanato bridges to form a planar 2D coordination polymer containing hexagonal metallocyclic rings [Cd(6)(SCN)(8)(hmt)(2)]. A 2D layer structure is held together with its neighboring ones via a set of hydrogen-bonding interactions to form a 3D supramolecular structure. The luminescent properties of the title complex in the solid state were investigated.

(Benzene-1,3-dicarboxyl-ato-κO,O)(1,12,15,26-tetra-aza-5,8,19,22-tetra-oxa-3,4:9,10:17,18:23,24-tetra-benzocyclo-octa-cosane-κN,N,N,N)cadmium(II) benzene-1,3-dicarboxylic acid solvate

In the title compound, [Cd(C₈H₄O₄)(C₃₆H₄₄N₄O₄)]·C₈H₆O₄, the Cd^II atom is six-coordinated by four N atoms from the macrocyclic ligand and two O atoms from a benzene-1,3-dicarboxyl­ate ligand. The complex mol­ecules are linked by N—H⋯O hydrogen bonds, forming a one-dimensional chain structure along the b axis. The chains are further connected through N—H⋯O and O—H⋯O hydrogen bonds between the complex mol­ecule and an uncoordinated benzene-1,3-dicarboxylic acid mol­ecule, resulting in a two-dimensional supra­molecular network.
