Abstract
In the title cobalt(II) coordination polymer with isobutyrate ligands, {[Co{CH(CH3)2CO2}2(H2O)]·H2O}n, the Co2+ ion is hexacoordinated in a slightly distorted octahedral coordination environment defined by two O atoms from two bridging water molecules and four O atoms from four bridging carboxylate ligands. The carboxylates adopt two different coordination modes, μ-(κ2O:O′) and μ-(κ2O:O), forming a one-dimensional polymeric chain extending along [010]. The intra-chain cobalt⋯cobalt separation is 3.2029 (2) Å. The polymeric chains are linked by hydrogen bonds involving the water molecules of solvation, giving a two-dimensional network structure lying parallel to (100).
