Abstract
The crystal structures of the title compounds have been determined from three-dimensional X-ray diffractometer data by conventional Patterson and Fourier methods. Both compounds crystallize in the orthorhombic space group P212121, with Z= 4; cell parameters for the ammonia derivative (II) are: a= 10·540(5), b= 13·147(6), and c= 10·443(5)Å; those of the triphenylphosphine derivative (I) are: a= 17·211(8), b= 14·225(6), and c= 10·656(5)Å. The structures were refined by least-squares methods to R 0·038 [(II), 1651 observed reflections] and 0·049 [(I), 1429 observed reflections]. Evidence for trans-influence in this type of octahedral cobalt(III) complex is discussed.Keywords
