摘      要：A new polyborate containing ehiral metal-complex Zn（en）3 B5O7（OH）3, where en = ethylenediamine, was synthesizedunder solvothermal conditions and structurally characterized by means of X-ray diffraction analysis. Crystal data： Zn（en）3 B5O7（OH）3, monoclinic, space group P21/c, a =0.8532（72） nm, b =2.3340（5） nm, c = 0.9526（92） nm, β =107. 04（3）°, Z=4, V=1.8140（6） nm^3, Dc =1.694 g/cm^3, p=1.416 mm^-1, F（000） = 960, GOF = 1. 020, R =0. 0276, Rw =0. 0828. There is a chiral Zn（en）3^2＋ complex cation and an isolated B5O7（OH）3^2- group in a Zn（en）3 B5O7（OH）3 molecule. The enantiomer of the chiral complex cation is separated orderly as ,4 and A configurations in the compound and the borate group consists of two B303 cycles linked through a bridging boron atom.
