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}4Cl2]·3MeCN(2), [Ni(SO4)(H2O){(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. 相似文献
