T The title compound,[Zn2(H2C4BIm)(ox)2]·2H2O(1,H2C4BIm=2,2'-(1,4-butanediyl)bis(1H-benzimidazole),has been synthesized by the hydrothermal reaction of space group P-1 with α=9.445(9),b=9.598(9),c=14.962(14)(A),α=72.160(I0),β=79.905(12),γ=83-680(11)°,Mr=633.18,V=1269(2)(A)3,Z=2,Dc=1,657 g/cm3,F(000)=644,μ=1.953mm-1,the final R=0.0671 and wR=0.1689.X-ray crystal structure analysis revealed that 1 is a 3Dnetwork with(203)2(20)3 topology in which the ZnⅡ atom can be considered as a 3-counected node and both ox2-and H2C4BIm serve as the linear linkers.
