摘要：A novel 12-ring network coordination polymer，[{[Cu(C4 N2H10)4]2H4V4O14} (denoted as QUST-4)，has been hydrothermally synthesized and structurally determined by X ray single-crystal difraction analysis．QUST-4 was crystallized in a monoclinic system with space group P21／n．The parameters of the unit cell are a=1.0497(2)nn，b= 1.6728(3)nm，c=1.2857(3)nm， b=94.14(3)，V=2.2517(8)nm，z=4，Dc= 1.841 Mg／m3，Rl=0.1071，and wR=0．2703．The largest diference peak and hole were 2284 an -1040 e/nm3，respectively．The SBU (secondary building unit)of QUST-4 was a new cycle-aggregate of polyoxovanadate cycle-[H4V4Ol4]42-，diferent from cycle．[V4Ol2]，which was condensed from two tetrahedral and two trigonal bipyramids via alternate arrangement．Cu(piper)4(piper=piperazine)group connected the cycle-[H4V4Ol4] anions to form the 12。ring network．The adjacent layers were linked by van der Walls forces．
