Abstract
- The title compound, [Sr(C9H5INO4S2)2(H2O)2]·H2O, is isomorphous with the corresponding calcium complex of ferron (8-hydroxy-7-iodo­quinoline-5-sulfonic acid). The asymmetric unit consists of one SrII ion, two organic ligands, two coordinated water mol­ecules and one uncoordinated water mol­ecule. The SrII ion has a pentagonal–bipyramidal coordination geometry made up of O atoms of three different sulfonate groups, deprotonated quinolinol O atoms of two different oxine rings and two water mol­ecules. In the ligands of type I, two O atoms of the sulfonate group are involved in coordination, whereas in type II ligands, only one O atom is involved. Ligands of type I are stacked on top of one another, each pair of adjacent members of the stack being related by an inversion centre. Ligands of type II are also stacked in a similar manner. These molecular stacks are cross-linked by Sr—O(sulfonate) and Sr—O(quinolinol) bonds, leading to an extended framework. This architecture is further stabilized by a number of O—H⋯O and N—H⋯O hydrogen bonds. [ABSTRACT FROM AUTHOR]
