Abstract

In the title layered coordination polymer, [Sr(C8H10O4)](n), the strontium ion adopts a distorted square-antiprismatic SrO8 geometry, arising from its coordination by six different ciscyclohexane-1,2-dicarboxylate dianions (two bidentate and four monodentate). Within the dianion, the cyclohexane ring adopts a chair conformation and the dihedral angle between the planes of the -CO2- groups is 80.4 (6)degrees. The polyhedral linkage pattern leads to (100) sheets in the crystal in which the SrO8 groups share triangular faces and edges in which the Sr center dot center dot center dot Sr topological connectivity is a 6(3) net. The crystal studied was a nonmerohedral twin, with the components related by a 180 degrees rotation about [100].
