In order to investigate the influence of organic groups on the structural types of organoa- rsenic polymolybdates,benzylarsonic acid has been selected to react with sodium molybdate.Three new complexes have been synthesized and characterized:[C(NH_2)_3]_4 [(C_6H_5CH_2As)_2Mo_6O_(24)](1), Cs_4[(C_6H_5CH_2As)_2Mo_6O_(24)]·5H_2O(2)and[(n-C_4H_9)_4N]_3Na[(C_6H_5CH_2As)_2Mo_6O_(24)].6H_2O(3).Molecular structure of compound 1 has been determined by means of single-crystal X-ray diffraction studies.It is monoclinic,space group P2_1/n with cell dimensions of a=12.342(2),b=18.621(2),c=10.042(2), β=105.80(1)°,V=2220.5~3,z=2,μ=15.854cm^(-1),R=0.023.It is demonstrated that the structural types of benzylarsonic polymolybdates are the same as those for alkylarsonic polymolybdates but different from those for arylarsonic polymolybdates.Their elemental analyses,IR and UV spectra and electrochemical behaviors in aqueous solution have been reported.It is suggested that the arsenic- carbon bond has great influence on the structural types of organoarsenic polymolybdates. 展开更多
