| Özet |
| The asymmetric unit of the title polymeric compound, [Cu(C8H4NO2)2(C10H14N2O)(H2O)]n, contains one CuII atom, one coordinating water molecule, two 4-cyanobenzoate (CB) ligands and one coordinating N,N-diethylnicotinamide (DENA) molecule. The DENA ligand acts as a bis-monodentate ligand, while the CB anions are monodentate. Two O atoms of the CB ligands, one O atom of the water molecule and the pyridine N atom of the DENA ligand form a slightly distorted square-planar arrangement around the CuII atom which is completed to a square-pyramidal coordination by the apically placed O atom of the DENA ligand, with a Cu - O distance of 2.4303(15)Å. In the two CB anions, the carboxylate groups are twisted relative to the attached benzene rings by 2.19(12) and 3.87(15)°, while the benzene rings are oriented at a dihedral angle of 5.52(8)°. The DENA ligands bridge adjacent Cu2+ ions, forming polymeric coordination chains running along the b axis. In the crystal, strong water-carboxylate O - H···O hydrogen bonds link adjacent chains into layers parallel to (10-1) and weak C - H···O hydrogen bonds further stabilize the crystal structure. The cyano group C and N atoms of one of the CB ligands are disordered over two sets of sites with equal occupancies. |
