摘要
Two new gallium antimony sulfides,[enH2][Ga2Sb2S7]·en（1） and [puH]2[Ga2Sb2S7]（2）（en = ethylenediamine,pu = propyleneurea）,have been solvothermally synthesized.In the pre-paration of compound 2,the protonated propyleneurea cation as counterion and template was in situ synthesized by the reaction of 1,3-diaminopropane with CO2 in pyridine.Both structures contain a two-dimensional network composed of novel heterometallic clusters of {Ga2Sb2S9} as the second-dary building unit.The thermal and optical properties of compounds 1 and 2 were characterized by TGA and UV-Vis,respectively.
