摘要 The employment of N-hydroxy-pyridine-2-carboxamidine in the coordination chemistry of zinc（II）, nickel（II） and manganese（II） under solvothermal conditions is reported. Four complexes of compositions, [Zn2（O2CMe）3{（py）C（NH2）NOH}4]（OH） （1）, [Zn4（OH）2{（py）C（NH2）- NO}4CI2]＇3MeCN （2）, [Ni（SO4）（H20）{（py）C（NH2）NOH}2]＇H2O （3） and [Mn（SO4）{（py）C（NH2）- NOH}2]n （4）, have been synthesized by rationally choosing different metal salts and dexterously employing acetate and sulfate ions as the bridging groups. Luminescent properties for 2 suggested strong emission in the solid state at room temperature. Variable temperature （2.0-300 K） magnetic studies for the linear chain complex 4 indicate weak antiferromagnetic Mn（Ⅱ）...Mn（Ⅱ） exchange interactions.
