Crystal structure of trans-di-aqua-bis-(4-cyano-benzoato-?O)bis-(N,N-di-ethyl-nicotinamide-?N)zinc(II).

ABSTRACT: In the title complex, [Zn(C8H4NO2)2(C10H14N2O)2(H2O)2], the ZnII cation, located on an inversion centre, is coordinated by two water mol-ecules, two 4-cyano-benzoate (CB) anions and two di-ethyl-nicotinamide (DENA) ligands in a distorted N2O4 octa-hedral geometry. In the mol-ecule, the dihedral angle between the planar carboxyl-ate group and the adjacent benzene ring is 9.50?(14)°, while the benzene and pyridine rings are oriented at a dihedral angle of 56.99?(5)°. The water mol-ecules exhibit both an intra-molecular hydrogen bond [to the non-coordinating carboxyl-ate O atom, enclosing an S(6) hydrogen-bonding motif, where O?O = 2.6419?(19)?Å] and an inter-molecular hydrogen bond [to the amide carbonyl O atom, enclosing an R22(16) ring motif, where O?O = 2.827?(2)?Å]; the latter lead to the formation of supra-molecular chains propagating along the [110] direction.
