Abstract: A novel 12-ring network coordination polymer, {[Cu(C4N2H10)4]2H4V4O14}n(denoted as QUST-4), was hydrothermally synthesized and structurally determined by X-ray single-crystal diffraction 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) nm, b=1.6728(3) nm, c=1.2857(3) nm, β=94.14(3)°, V=2.2517(8) nm3, Z=4, Dcal= 1.841 Mg/m3, R1=0.1071, and wR3=0.2703. The largest difference peak and hole were 2284 and -1040 e/nm3, respectively. The SBU(secondary building unit) of QUST-4 was a new cyclo-aggregate of polyoxovanadate cyclo-[H4V4O14]4-, different from cyclo-[V4O12]4-, which was condensed from two tetrahedral and two trigonal bipyramids via alternate {arrangement.} Cu(piper)4(piper=piperazine) group connected the cyclo-[H4V4O14]4- anions to form the 12-ring network. The adjacent layers were linked by van der Walls forces.
