Abstract

In the crystal structure of the title compound, poly[tri-μ-formato-cobalt(II)potassium], [CoK(CHO2)3]n the Co2+ cations are coordinated by six O-bonded formate anions in an octa­hedral coordination mode and the K+ cations are eightfold coordinated by seven O-bonded formate anions within irregular polyhedra. The Co2+ cations are connected by bridging formate anions into a three-dimensional coordination network in which the K+ cations are embedded. The asymmetric unit consits of one Co2+ cation located on a center of inversion, one K+ cation located on a twofold axis and two crystallographically independent formato anions, of which one is located on a twofold axis and the other occupies a general position.
