Bis[μ-N-(diethyl­amino-κN)dimethyl­silylanilido-κ(2) N:N]bis­[chlorido­cobalt(II)]

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 mol­ecule. 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 tetra­hedral 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.
