33(4)°, and Z= 4. Least-squares refinement gives R= 0.066 for the 1 881 observed reflections. The nickel atom is five-co-ordinated by one sulphur and four phosphorus atoms of the macrocycle according to a distorted trigonal-bipyramidal geometry. The stereochemistry of some cobalt(II) and nickel(II) complexes of this ligand are investigated in the solution and in the solid state by electronic spectroscopy
