Crystal and molecular structure of bis(N-cyclohexylthiopicolinamidato)copper(II)

Abstract

The structure of the title compound (I) has been determined from single-crystal three-dimensional X-ray photographic data. The structure was solved by Patterson and Fourier methods, and refined by least-squares techniques to R 0·059 for 1911 independent reflections. All the hydrogen atoms were located and their parameters were refined. The compound is molecular with the copper atom bonding in a trans-square planar manner to the thioamido-sulphur atoms and the pyridyl nitrogen atoms of two N-cyclohexylthiopicolinamidato-chelates [Cu–S 2·252(2), Cu–N 2·048(4)Å]; carbon atoms from adjacent molecules are situated at 3·4 Å above and below the co-ordination plane of the copper atom. The unit cell is triclinic with Z= 1, a= 5·223(7), b= 10·600(4), c= 11·573(4)Å, α= 111·2(1), β= 96·8(1), γ= 92·0(1)°, space group P.
