Crystal and molecular structure of the five-co-ordinate high-spin complex {[2-{[2-(diethylamino)ethyl]amino}ethyl]diphenylphosphine oxide} di-isothiocyanatocobalt(II)
Abstract
The crystal and molecular structure of the title compound has been determined by X-ray diffraction techniques, from 1258 reflections collected by photographic methods. The complex crystallises in the monoclinic space group P21/c, with a= 9·518(1), b= 16·310(1), c= 16·532(1)Å, β= 100·59(1)°, Z= 4. The structure was solved by Patterson and Fourier methods and refined by full-matrix least-squares procedures to R 9·5%.
The structure consists of distorted trigonal bipyramids, with two nitrogen and one oxygen atoms forming the equatorial plane and two nitrogen atoms at the apices.
