Abstract

The first organically templated gallium oxalatophosphonate has been synthesized under hydrothermal conditions and characterized by single-crystal X-ray diffraction, infrared spectroscopy, and thermogravimetric analysis. The structure consists of GaO(6) octahedra and GaO(4) tetrahedra connected by methylphosphonate and bis-bidentate oxalate anions to form anionic sheets in the ab plane with the charge-compensating propylenediammonium cations and water molecules between the sheets. The methyl groups of the phosphonate ligands extend from both sides of the layers into the interlamellar region. Crystal data: monoclinic, space group P2(1)/n (No. 14), a = 8.8514(4) A, b = 16.3030(7) A, c = 15.0816(7) A, beta = 97.539(1) degrees, and Z = 4.

摘要

首个有机模板草酸镓膦酸盐已在水热条件下合成，并通过单晶X射线衍射、红外光谱和热重分析进行了表征。该结构由GaO(6)八面体和GaO(4)四面体组成，它们通过甲基膦酸盐和双齿草酸根阴离子连接，在ab平面上形成阴离子层，层间有电荷补偿的丙二铵阳离子和水分子。膦酸盐配体的甲基从层的两侧延伸到层间区域。晶体数据：单斜晶系，空间群P2(1)/n（编号14），a = 8.8514(4) Å，b = 16.3030(7) Å，c = 15.0816(7) Å，β = 97.539(1)°，Z = 4。
