In the two-dimensional title coordination polymer, [Zn(C8H4O4)(C14H14N4)] n , the ZnII atom adopts a distorted tetrahedral geometry, being ligated by two O atoms from two different benzene-1,3-dicarboxylate dianions and two N atoms from two symmetry-related 1,2-bis(imidazol-1-ylmethyl)benzene molecules. The dihedral angles between the imidazole rings and the benzene ring in the neutral ligand are 76.31 (13) and 85.33 (15)°. The ZnII atoms are bridged by dicarboxylate ligands, forming chains parallel to the a axis, which are further linked by 1,2-bis(imidazol-1-ylmethyl)benzene molecules, generating a two-dimensional layer structure parallel to the ac plane. The crystal structure is enforced by intralayer and interlayer C—H...O hydrogen bonds.

A novel manganese coordination polymer, poly[(μ5-thiophene-3,4-dicarboxylato)manganese(II)], [Mn(C6H2O4S)]n, was synthesized hydrothermally using 3,4-thiophenedicarboxylate (3,4-tdc2−) as the organic linker. The asymmetric unit of the complex contains an Mn2+cation and one half of a deprotonated 3,4-tdc2−anion, both residing on a twofold axis. Each Mn2+centre is six-coordinated by O atoms of bridging/chelating carboxylate groups from five 3,4-tdc2−anions, forming a slightly distorted octahedron. The Mn2+centres are bridged by 3,4-tdc2−anions to give an infinite two-dimensional layer which incorporates one-dimensional Mn–O gridlike chains, and in which the 3,4-tdc2−anion adopts a novel hexadentate chelating and μ5-bridging coordination mode. The fully deprotonated 3,4-tdc2−anion exhibits unexpected efficiency as a ligand towards the Mn2+centres, which it coordinates through all of its carboxylate O atoms to provide the novel coordination mode. The IR spectrum of the complex is also reported.

AbstractA new two-dimensional ZnII coordination framework [Zn(1,3-BMIB) (OBA)]n (1) (where H2OBA is 4,4ʹ-oxy-bis(benzoic acid) and 1,3-BMIB is 1,3-bis(2-methyl-1-imidazolyl)benzene) has been prepared and characterized through IR spectroscopy, elemental and thermal analysis, and single-crystal X-ray diffraction. Complex 1 is a (4, 4) grid coordination polymer with a layer structure. It exhibits high photocatalytic degradation effects upon UV irradiation of methylene blue and methylene orange aqueous solutions.

In the title coordination polymer, [Ag2(C4H4O4S)], each AgIcation is four-coordinated by three of the four carboxylate O atoms and the S atom from symmetry-related sulfanediyldiacetate ligands, thus defining a distorted tetrahedral geometry at the metal centre. The AgIcations are bridged by sulfanediyldiacetate groups, leading to a two-dimensional layer structure. These layers are interconnectedviaAg—S bonds to form a three-dimensional coordination polymer network overall.

The two-dimensional coordination polymer [Ni(bpdc)(bix)1.5 ·H2O]n (H2bpdc = 2,4’-biphenyldicarboxylic acid; bix = 1,4-bis(imidazol-1-ylmethyl)benzene) was hydrothermally synthesized and structurally characterized. In the tile compound, the octahedral coordination environment around the Ni2+ ion is established by two oxygen atoms from two bpdc2− anions, one water molecule and three nitrogen atoms from three bix ligands. One bix ligand in the asymmetric unit lies on an inversion center at 1, 0.5, 0.5, and the other bix molecule resides on a general position. Each of the two bix molecules is coordinated to four Ni2+ ions, forming a 52-membered ring which is further assembled into a one-dimensional tape structure running parallel to the [100] direction. By a combination of the O2 and O4 oxygen atoms of one bpdc2− anion coordinating two Ni2+ ions, adjacent tapes are joined together, forming a layer structure parallel to the (010) plane. A 22-membered ring is formed by means of two bpdc anions binding to two Ni2+ ions.
