摘要

A three-dimensional supramolecular architecture, {[Co(proH)(H2O)3]2[P2Mo5- O23]}·7H2O (1, pro = praline), has been synthesized and characterized by IR, elemental analysis, thermogravimetric analysis, and single-crystal X-ray diffraction. 1 crystallizes in monoclinic, space group C2 with a = 20.600(3), b = 11.6980(11), c = 9.2944(10) , β = 107.837(4)°, V = 2132.1(4) 3, Z = 2, C10H46Co2Mo5N2O40P2, Mr = 1493.99, Dc = 2.327 g/cm3, F(000) = 1468, μ(MoKα) = 2.375 mm-1, the final R = 0.0339 and wR = 0.0844 for 4169 observed reflections with I > 2σ(I). Single- crystal X-ray crystallographic analysis reveals that the helical water chains and {[Co(proH)- (H2O)3]2[P2Mo5O23]}n chains are perpendicular to each other and extend into an overall three-di- mensional supramolecular architecture by hydrogen-bonding interactions. The magnetic investi- gation indicates weak antiferromagnetic interactions in the compound.
