The salts [Fe(C5Me5)2][M(C2B9H11)2)], (M = Cr, Fe, Ni), have been prepared by metathesis of [Fe(C5Me5)2]Cl and [(CH3)4N][M(C2B9H11)2], (M = Cr, Fe, Ni), and the three salts have been shown to be isostructural from powder X-ray diffraction studies. The structure of the salt [Fe(C5Me5)2][Fe(C2B9H11)2)] has been determined by a single crystal X-ray diffraction study.The anions and cations pack in a distorted
盐[Fe(C 5 Me 5)2 ] [M(C 2 B 9 H 11)2)],(M = Cr,Fe,Ni),是通过[Fe(C 5 Me 5)复分解制备的。2 ] Cl和[(CH 3)4 N] [M(C 2 B 9 H 11)2 ],(M = Cr,Fe,Ni),三种盐从粉末X射线显示为同构衍射研究。盐[Fe(C 5 Me 5)2 ] [Fe(C 2 B 9 H11)2)]是通过单晶X射线衍射研究确定的。阴离子和阳离子堆积在扭曲的CsCl型结构中,认为该畸变是由[Fe(C 2 B 9 H 11)2)] -阴离子。这三种盐的固态磁化率数据都可以在6到296 K之间拟合居里-威斯定律。θ值低表明没有明显的铁磁或反铁磁即使在低温下,未配对的自旋之间也会发生相互作用。
