摘要：

An organic-inorganic hybrid 1D helical chain arsenomolybdate {[Cu(en)(2)][Cu(en)(H2O)][(Cu(en)(2)(H2O)] [(AsAsMo9O34)-As-III-Mo-V]} center dot 2H(2)O (1) (en = ethylenediamine) has been hydrothermally synthesized and characterized by elemental analyses, IR, UV and CD spectrum, powder X-ray diffraction, TG-DTA and single-crystal X-ray diffraction. The asymmetric unit of 1 consists of a monocapped trivacant Keggin [(AsAsMo9O34)-As-III-Mo-V](6-) a pendant [Cu(en)(2)(H2O)](2+) cation, a pendant [Cu(en)(H2O)](2+) cation, one bridging [Cu(en)(2)](2+) cation and two lattice water molecules. It should be noted that I illustrates a one-dimensional (1D) helical chain assembled by {[Cu(en)(H2O)][(Cu(en)(2)(H2O)][(AsAsMo9O34)-As-III-Mo-V)]}(2-) clusters and [Cu(en)(2)](2+) linkers.
