Abstract

Abstract : The crystal structure of [Sr2 (BTEC)(H2 O)] n (BTEC is benzene‐1, 2, 4, 5‐tetracarboxylate) has been studied using X‐ray diffraction, vibrational spectroscopy and thermal methods. The extended three‐dimensional framework contains two‐dimensional inorganic layers connected through organic linkers. Abstract : Coordination of the anions of benzenecarboxylic acids with metal cations leads to coordination polymers with various structural features. Very few examples of strontium‐based structures have been reported. A new three‐dimensional coordination polymer, namely poly[aqua(μ12 ‐benzene‐1, 2, 4, 5‐tetracarboxylato)distrontium(II)], [Sr2 (C10 H2 O8 )(H2 O)] n, has been synthesized under hydrothermal conditions and characterized by thermal analysis, vibrational spectroscopy (Raman and IR), single‐crystal X‐ray diffraction and powder X‐ray diffraction. The coordination geometries around the two independent Sr II ions can be described as a distorted dodecahedron and a distorted monocapped square antiprism. The compound features a three‐dimensional structure containing inorganic motifs, with two‐dimensional layers connected through organic linkers, and possesses a topologic structure of a binodal (6, 12) connected alb net with the Schläfli symbol {4 15 }2 {4 48 .6 18 }. The final product of thermal decomposition is strontium oxide (SrO).
