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

Abstract

The title compound, [Co(C16H23O2)2(C3H4N2)2] or (C3H4N2)2Co(O2CC6H2 iPr3-2,4,6), is a rare example of a tetra­coordinate cobalt(II) carboxyl­ate stabilized by ancillary N-heterocyclic ligands. The Co(II) ion resides on a crystallographic twofold axis so that the asymmetric unit comprises one half-mol­ecule. Due to the steric bulk of the 2,4,6-triisopropyl­phenyl substituents, the carboxyl­ate ligands are both coordinated in a monodentate fashion despite the low coordination number. The coordination geometry around the central Co(II) ion is distorted tetra­hedral with angles at Co ranging from 92.27 (18)° to 121.08 (14)°
