摘　　要：TWO complexes of compositions [Zn（H2shi）（CHsCOO）]. （1） and [Cd（H2shih（H20）]. （2） （H3shi = salicylhydroxamic acid） have been prepared under solvothermal conditions. They are characterized by X-ray single-crystal diffraction, IR and elemental analysis. The crystal of 1 belongs to the tetragonal system, space group I41/a with a = 18.972（3）, b = 18.972（3）, c = 10.938（2） A, V= 3937.1（I） A3, C9H9NOsZn, Mr - 276.54, Z = 16, Dc = 1.866 g/cm3,μ = 2.500 mm-1, F（000） = 2240, the final R = 0.0425 and wR = 0.123. The crystal of 2 belongs to the monoclinic system, space group P2/c with a = 16.647（3）, b = 6.4577（I）, c = 6.5623（I） A, V = 702.4（2） A3, C14H4Cd2N2OT, Mr = 434.68, Z = 2, Dc = 2.055 g/cm3,μ = 1.599 mm-1, F（000） = 432, the final R = 0.0211 and wR = 0.0761. They both possess I-D polymeric chain structures. The luminescent properties of complexes I and 2 have been investigated.TWO complexes of compositions [Zn（H2shi）（CHsCOO）]. （1） and [Cd（H2shih（H20）]. （2） （H3shi = salicylhydroxamic acid） have been prepared under solvothermal conditions.
