چکیده
In the title compound, {[Zn(C8H4O4)(C6H6N2O)2]·C6H6N2O} n , the Zn(II) ion exhibits a tetra-hedral coordination environment defined by two benzene-1,4-dicarboxylate dianions and two 4-pyridinealdoxime ligands. The dianions bridge the Zn(II) ions, giving a zigzag chain along the b axis. Adjacent chains are connected by O-H⋯O hydrogen bonds, forming a cavity in which an uncoordinating 4-pyridine-aldoxime mol-ecule is located; this mol-ecule is linked by O-H⋯O and O-H⋯N hydrogen bonds to the zigzag chain.

In the title coordination polymer, [Zn(C(8)H(4)O(4))(C(5)H(5)N)(2)](n), the Zn(II) atom, located on a twofold rotation axis, is tetra-coordinated by two monodentate O atoms from two different carboxyl-ate groups and two pyridyl N atoms, forming a distorted tetra-hedral geometry. The Zn(II) atoms are bridged by terephthalate ligands, generating an infinite zigzag chain along [101].

In the title compound, [Pd(C(8)H(4)O(4))(C(7)H(6)N(2))(2)](n), the Pd atom is tetra-coordinated by two carboxyl-ate O atoms from two benzene-1,4-dicarboxyl-ate (bdc) dianions and two N atoms from two benzimidazole ligands, resulting in a slightly distorted tetra-hedral PdO(2)N(2) geometry. The bdc ligand acts as a bridge, linking the Pd atoms into a chain. Inter-chain N-H⋯O hydrogen bonds help ...
