摘要：

A magnetochemical study has been performed on a series of [M-II(1,10-Ct(2)H(8)N(2))(3)](2+) (M-II = Mn, Ni, Cu) cation salts with [B9C2H12](-) and [M-III(B9C2H11)(2)](-) (M-III = Co, NO ortho-carboranes(12) in the temperature range of 2 K to 300 K. X-ray diffraction (XPD) and X-ray phase analysis (XRPA) data are given and discussed for these compounds. The complexes contain paramagnetic centers of different origin and aromatic fragments of two types in the structures. The results arc represented by the temperature (T) dependences of the inverse molar paramagnetic susceptibility (chi(-1)) and effective magnetic moments (mu(ef)) and by Curie-Weiss equations. For two salts with Mn(II), ferromagnetic interactions near T = 20 K have been detected, which is a new phenomenon in borane chemistry.
