| Popis: | Each of the carboxylate –CO2 fragments of the dianion ligand in the title compound, {[Sr(C9H4N2O4)(H2O)2]·H2O}n, chelates to a SrII atom and at the same time, one of the two O atoms coordinates to a third SrII atom. The μ4-bridging mode of the dianion generates a square-grid layer motif; adjacent layers are connected by O—H...O, O—H...N and N—H...O hydrogen bonds, forming a three-dimensional network. The eight-coordinate Sr atom exists in a distorted square-antiprismatic geometry. The crystal studied was a non-merohedral twin with a minor twin component of 24%. |
