title: Crystal structure oftrans-di-aqua-bis-(4-cyano-benzoato-κO)bis-(N,N-di-ethyl-nicotinamide-κN)cadmium.
abstract: The mononuclear title cadmium complex, [Cd(C10H14N2O)2(C8H4NO2)2(H2O)2], is centrosymmetric and contains two water mol-ecules, two 4-cyanobenzoate (CB) ligands and two di-ethyl-nicotinamide (DENA) ligands. All the ligands are coordinated to the CdIIatom in a monodentate mode. The four nearest O atoms around the CdIIatom form a slightly distorted square-planar arrangement, with the distorted octa-hedral coordination sphere being completed by the two pyridine N atoms of the DENA ligands at distances of 2.3336 (13) Å. The dihedral angle between the carboxyl-ate group and the adjacent benzene ring is 8.75 (16)°, while the benzene and pyridine rings are oriented at a dihedral angle of 57.83 (5)°. The water mol-ecules exhibit both intra-molecular [to the non-coordinating carboxyl-ate O atom, enclosing anS(6) hydrogen-bonding motif, where O⋯O = 2.670 (2) Å] and inter-molecular [to the amide carbonyl O atom, enclosing anR22(16) ring motif, where O⋯O = 2.781 (2) Å] O-H⋯O hydrogen bonds. The latter lead to the formation of supra-molecular chains propagating along [110].
