A new zinc 1,3,5-benzenetricarboxylate Zn3(BTC)2(DMSO)4(BTC=1,3,5-benzenetricarboxylate) has been solvothermally synthesized in DMSO and structurally determined by X-ray single-crystal diffraction.It crystallizes in the monoclinic system,space group P21/c with a=10.0861(11),b=10.2527(11),c=16.4013(18),β=95.478(2)°,V=1688.3(3)3,Z=2,Zn3S4C26H30O16,Mr=922.85,Dc=1.815 g/cm3,F(000)=936,μ=2.434 mm-1,R=0.0319 and wR=0.0755.This compound consists of trimeric zinc clusters and BTC linkers.Alternate connection of these trimeric zinc clusters and BTC linkers results in a three-dimensional(3,6)-connected frame-work with rutile topology.
