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. 展开更多
