The macrocycle 5,8,16,19-tetraphenyl-1,12-dithia-5,8,16,19-tetraphosphacyclodocosane, L³, has been synthesised in 13percent yield.Three of the five possible diastereoisomers are isolated and one of them (β) is used to form cobalt(II) and nickel(II) complexes with 1 : 1 and 2 : 1 metal-ligand ratios.The compound 3)>2*MeOH crystallises in the orthorhombic space group Pbca with a = 17.791(4), b = 20.993(4), c = 22.758(5) Angstroem, and Z = 4.Least-squares refinement gave R =0.092, for the 917 observed reflections.The cation 3)>²⁺ contains two nickel atoms in a slightly distorted square-planar environment related by a crystallographic centre of symmetry.Each nickel atom is co-ordinated by two phosphorus and one sulphur atoms of the macrocycle and by one bromide ion.The Ni...Ni separation within the cation is 5.13 Angstroem.The stereochemistries of some cobalt(II) and nickel(II) complexes of β-L³ have been investigated in solution and in the solid state by electronic and 31P n.m.r. spectroscopy, and by magnetic measurements.
