Abstract

The polymeric title compound, {[Co(C15H9NO4S)(H2O)3]·H2O}n, consists of chains along [001] made up from Co2+ ions bridged by 10-methyl­phenothia­zine-3,7-dicarboxyl­ate anions. The Co2+ ion, coordinated by three O atoms from two different carboxyl­ate groups and three water mol­ecules, displays a distorted octa­hedral environment. In the crystal, π–π inter­chain inter­actions, with centroid–centroid distances of 3.656 (2) and 3.669 (2) Å between the benzene rings of the ligands, assemble the chains into sheets parallel to (100). O—H⋯O hydrogen-bonding inter­actions between the coordinating water mol­ecules and carboxyl­ate O atoms link the sheets into a three-dimensional network.
