Diaqua-bis-(N,N-diethyl-nicotinamide-κN)bis-(4-ethyl-benzoato-κO)cobalt(II).

The title Co(II) complex, [Co(C(9)H(9)O(2))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], contains two 4-ethyl-benzoate (PEB), two monodentate diethyl-nicotinamide (DENA) ligands and two water mol-ecules. The four O atoms in the equatorial plane around the Co(II) ion form a slightly distorted square-planar arrangement, while the slightly distorted octa-hedral coordination is completed by the two N atoms of the DENA ligands in the axial positions. Intra-molecular O-H⋯O hydrogen bonds link the water mol-ecules to the carboxyl-ate groups. The dihedral angles between the carboxyl-ate groups and the adjacent benzene rings are 4.52 (18) and 4.56 (18)°, while the pyridine rings and the benzene rings are oriented at dihedral angles of 7.76 (10) and 5.67 (13)°. In the crystal, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into chains propagating along [010]. C-H⋯O inter-actions and a π-π contact between the pyridine rings [centroid-centroid distance = 3.476 (2) Å] are also observed.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
