摘要：

在常温条件下合成了铜-邻菲啰啉修饰的结构独特的多酸衍生物H4[Cu(phen)(H2O)][Cu(phen)][α-SiW11O39]·3H2O(1). 该化合物分子中2个独立的非二聚体的铜-邻菲啰啉平行地与缺位多酸空穴外的氧配位键合, 通过元素分析、红外光谱、热重分析和X射线单晶衍射对其结构进行了表征. 结果表明, 该化合物属三斜晶系, P1空间群, 晶胞参数a=1.3624(2) nm, b=1.4133(2) nm, c=2.0470(3) nm, α=97.840(3)°, β=95.117(3)°, γ=112.483(3)°.

Abstract:

A new monovacant polyoxometalates-based complex H4[Cu(phen)(H2O)][Cu(phen)][α-SiW11O39]·3H2O was synthesized under conventional conditions. In compound 1, two independent other than dimerized copper-phenanthroline graups are fused to the oxggen atoms in the vacant site of the mono-lacunary polyanton in parallel. It crystallizes in the triclinic space group P1 with a=1.3624(2) nm, b=1.4133(2) nm, c=2.0470(3) nm, α= 97.840(3)°, β=95.117(3)°, γ=112.483(3)°, V=3.5645(10) nm3, Dc=3.006 g /cm3, Z=2. Structure of compound 1 was characterized via elemental analysis, IR, single crystal XRD and cyclic voltammetry methods.
