Bis(1H-pyrazole-κN 2)bis(2,4,6-triisopropylbenzoato-κO)cobalt(II)

چکیده
The title compound, [Co(C(16)H(23)O(2))(2)(C(3)H(4)N(2))(2)] or (C(3)H(4)N(2))(2)Co(O(2)CC(6)H(2) (i)Pr(3)-2,4,6), is a rare example of a tetra-coordinate cobalt(II) carboxyl-ate stabilized by ancillary N-heterocyclic ligands. The Co(II) ion resides on a crystallographic twofold axis so that the asymmetric unit comprises one half-mol-ecule. Due to the steric bulk of the 2,4,6-triisopropyl-phenyl substituents, the carboxyl-ate ligands are both coordinated in a monodentate fashion despite the low coordination number. The coordination geometry around the central Co(II) ion is distorted tetra-hedral with angles at Co ranging from 92.27 (18)° to 121.08 (14)°.
