研究了一种含吡啶-2-醛肟酸单阴离子PyA的四核配合物[Cr（III）Mn（II）（3）（PyA）（6）Cl（3）] 1的结构和磁化学性质。该化合物是一个罕见的例子，四核星形金属拓扑结构含有吡啶-2-醛肟配体。静态磁性研究表明，顺磁中心（S（Cr）= 3/2和S（Mn）= 5/2）之间的反铁磁交换相互作用非常弱，导致紧密间隔的低位能级，发生分裂和交叉。初步的高场EPR测量（20 < nu < 388 GHz）表明存在0.7 cm（-1）量级的零场分裂D。
A tetranuclear complex [Cr(III)Mn(II)(3)(PyA)(6)Cl(3)] 1 containing pyridine-2-aldoximato monoanion, PyA, has been structurally and magnetochemically characterized. The compound is a rare example of a tetranuclear star-shaped metal topology containing pyridine-2-aldoximato ligands. Static magnetic studies have demonstrated very weak antiferromagnetic exchange interactions between the paramagnetic centers (S(Cr) = 3/2 and S(Mn) = 5/2) resulting in closely spaced low-lying levels, which undergo splitting and crossing. Preliminary high-field EPR measurements (20 < nu < 388 GHz) indicate the presence of zero-field splitting D of the order of 0.7 cm(-1).
