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]·MeCN (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.
