一维链状配位聚合物[Cu(en)_2]_2[Cu(en)_2·α-As_8~ⅢV_(14)~ⅣO_(42)(HPO_4)]·8H_2O的合成与晶体结构

Synthesis and Crystal Structure of a Chainlike Coordination Polymer [Cu(en)_2]_2[Cu(en)_2αAs_8~ⅢV_ (14)~ⅣO_ (42)(HPO_4)]·8H_2O

A novel coordination polymer, [Cu（en）2]2[Cu（en）2αAsⅢ8VⅣ 14O 42（HPO4）]·8H2O, was hydrothermally synthesized and structurally determined by Xray single crystal diffraction. The crystal belongs to monoclinic system, space group P2（1）/c, a=1.501 0（2） nm, b=1.860 9（3） nm, c=2.646 7（4） nm, β=102.169（5）°, V=7.227（2） nm3, Z=4, Dc=2.551 Mg/m3, F（000）=5 364. The structural refinement indicated that the tilted compound was a chainlike coordination polymer based on cluster [αAs8V 14O 42·（HPO4）] 6- as the building blocks. Two of the three Cu（en）2 groups acted as the balance cation and the other one connected the anion cage [αAs8V 14O 42（HPO4）] 6- to form the 1D chain.

The structural refine-ment indicated that the tilted compound was a chainlike coordination polymer based on cluster [ α-As8V14O42·（HPO4）]^6- as the building blocks. Two of the three Cu （en）2 groups acted as the balance cation and the other one connected the anion cage [ α-Ass V14O42（HPO4 ）]^6- to form the 1D chain.
