Bis[?-N-(diethyl-amino-?N)dimethyl-silylanilido-?N:N]bis-[chlorido-cobalt(II)].


ABSTRACT: In the title binuclear Co(II) complex, [Co(2)(C(12)H(21)N(2)Si)(2)Cl(2)], an inversion center is located at the mid-point between the two Co atoms in the dimeric mol-ecule. The bidentate N-silylated anilide ligand coordinates the Co(II) atom in an N,N'-chelating mode and provides the anilide N atom as a bridge to link two Co(II) atoms. The two ends of the N-Si-N chelating unit exhibit different affinities for the metal atom. The Co-N(anilide) bond is 2.031?(6)?Å and Co-N(amino) bond is 2.214?(6)?Å. The four-coordinate Co atom presents a distorted tetra-hedral geometry, while the dimeric aggregation exhibits a (CoN)(2) rhombus core with 1.998?(6)?Å as the shortest sides and shows a ladder structure composed of Co, N and Si atoms.
