摘要

在溶剂热条件下合成了三种新型金属取代磷酸镓(C3N2H5)8[Me8Ga16P24O96] (Me = Co, Fe, Mn),并用单晶x射线衍射测定了它们的结构。它们是等结构的,具有单斜对称,空间群C 2/ C,单位胞尺寸约为15 × 13 × 15 Å, β约为111°。这些材料都具有由PO4和MO4四面体(M = Me和Ga)交替构成的具有沸石拓扑结构(结构类型代码为LAU)的框架,其中咪唑阳离子占据了框架通道内的位点。磁化率测量表明,材料在很宽的温度范围内表现出居里-魏斯行为,过渡金属以二价阳离子的形式存在。

Synthesis and characterisation of transition-metal-substituted gallium phosphates with the laumontite structure

Three novel metal-substituted gallium phosphates, (C3N2H5)8[Me8Ga16P24O96] (Me = Co, Fe, Mn), have been synthesised under solvothermal conditions and their structures determined using single-crystal X-ray diffraction. They are isostructural, with monoclinic symmetry, space group C 2/c and unit-cell dimensions ca. 15 × 13 × 15 Å, β ca. 111°. The materials all have frameworks with the laumontite topology (structure type code LAU), constructed from alternating PO4 and MO4 tetrahedra (M = Me and Ga) with imidazole cations occupying sites within the channels of the framework. Magnetic susceptibility measurements show that the materials exhibit Curie-Weiss behaviour over wide ranges of temperature and that the transition metals are present as divalent cations.
