摘　　要：The zinc（Ⅱ） complex with Hpbx （Hpbx = 2-（benzoxazol-2-yl）phenol） and Hpbm （Hpbm = 2-（benzimidazol-2-yl）phenol）, namely [Zn（pbm）2]1.633[Zn（pbx）212.367·DMF·2H2O 1, has been synthesized and characterized by X-ray crystallography, FTIR and elemental analysis. The coordination structures are statistically disordered and can be regarded as a co-crystal of [Zn（pbm）2] and [Zn（pbx）2] with the ratio of ca. 0.408/0.592. Solvate water and DMF molecules are also present in the lattice. Crystal data for 1; monoclinic, space group P21/c, Mr= 2049.02, Z = 2, α = 9.7571（6）, b = 25.6415（16）, c = 19.8675（10） A, β= 111.342（2）°, V = 4629.7（5） A^3, Dc = 1.470 g/cm^3,μ = 1.100 mm^-1, F（000） = 2104, R = 0.0575 and wR = 0.1282 for 5528 observed reflections （I〉2σ（I））. The photoluminescent spectra for this compound have also been studied.The zinc（Ⅱ） complex with Hpbx （Hpbx = 2-（benzoxazol-2-yl）phenol） and Hpbm （Hpbm = 2-（benzimidazol-2-yl）phenol）, namely [Zn（pbm）2]1.633[Zn（pbx）212.367·DMF·2H2O 1, has been synthesized and characterized by X-ray crystallography, FTIR and elemental analysis.
