摘要：

Complexation of Ni-II ion with triethylenetetramine (teta) and potassium tricyanomethanide KC(CN)(3) yielded a new binuclear complex, [(teta)Ni(C(CN)(3))(2)Ni(teta)](ClO4)(2) (I), where two nickel(II) centres are held together by two tricyanomethanide bridges. The dinuclear units are aggregated into ladders; four of them being identified inside the unit cell. The effective magnetic moment on the cooling exhibits a slight gradual increase until. 25 K; below this limit a strong, abrupt ferromagnetic interaction culminating at 16 K appears.
