Abstract
In the title binuclear CoII complex, [Co2(C12H21N2Si)2Cl2], 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 CoII atom in an N,N′-chelating mode and provides the anilide N atom as a bridge to link two CoII atoms. The two ends of the N—Si—N chelating unit exhibit different affinities for the metal atom. The Co—Nanilide bond is 2.031 (6) Å and Co—Namino 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.

Summary
R factor = 0.072; wR factor = 0.227; data-to-parameter ratio = 18.7. In the title binuclear CoII complex, [Co2(C12H21N2Si)2Cl2], an inversion center is located at the mid-point between the two. The bidentate N-silylated anilide ligand coordinates the CoII atom in an N,N0 -chelating mode and provides the anilide N atom as a bridge to link two. The two ends of the N—Si—N chelating unit exhibit different affinities for the metal atom. The four-coordinate Co atom presents a distorted tetrahedral geometry, while the dimeric aggregation exhibits a (CoN) rhombus core with 1.998 (6) Å as the shortest sides and shows a ladder structure composed of Co, N and Si atoms.
