Abstract
Complexation of Ni-II ion with triethylenetetramine (teta) and potassium tr icyanomethanide 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 togethe r 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. 2 5 K; below this limit a strong, abrupt ferromagnetic interaction culminatin g at 16 K appears.
