摘要：

A new 2-D layer copper vanadium phosphate [Cu(4,4'-bipy)(VO)(HPO4)(H2PO4)](2) (4,4-bipy = 4,4'-bipyridine) 1 formed by the assemblage of two kind of I-D chains has been synthesized hydrothermally and characterized structurally. This compound was shown by single crystal structure analysis to be an unprecedented layer structure constructed from (Cu(4,4'-bipy))(2n)(2n+) chains linked in the second dimension by the [(VO)(HPO4)(H2PO4)](2n)(2n-) chains. In the packing arrangement, the structure can be viewed as a 3-D supramolecular framework connected by the combination of coordination bonds, hydrogen bonds and pi-pi interactions as well as weakly coordinative interactions. Another considerable feature is that we can isolate two helices from the [(VO) (HPO4) (H2PO4)](2n)(2n-) chain, respectively. Moreover, the two helices are both left-hand. Magnetic measurements indicate the existence of antiferromagnetic interactions in compound 1. (c) 2006 Elsevier SAS. All rights reserved.
