Unusual Behaviour of the Thioether Function of the Ligand 1,8-Bis(3,5-dimethyl-1-pyrazolyl)-3,6-dithiaoctane (bddo) towards Transition-metal Salts. X-Ray Structures of a Green and a Red Modification of
Co-ordination compounds of the new ligand 1,8-bis(3,5-dimethyl-1-pyrazolyl)-3,6-dithiaoctane (bddo) with MCl2 (M = Fe, Mn, Ni, Co, Zn, Cu, or Cd), MBr2 (M = Mn, Co, Ni, or Zn), Cu(BF4)2, and CuX (X = BF4, NCS, Cl, Br, or I) are described.The general formula for the divalent metal is and for copper(I), .With CuCl2 two modifications were obtained.The green modification of crystallises in space group P21/n with a = 9,019(2), b = 28,671(5), c = 8,431(2) Angstroem, beta = 113,65(2) deg, R = 0,055, and R’= 0,066 for 1578 unique reflections 2?(I)>.The compound consists of Cu(bddo)Cl2 units.The copper atom is co-ordinated by two pyrazole nitrogens and two chloride atoms, in trans positions, in a distorted square-planar geometry.The red modification of crystallises in space group Pbcn with a = 9,397(4), b = 15,093(4), c = 15,142(4) Angstroem, Z = 4, R = 0,069, and R’= 0,089 for 864 unique reflections ?(I)>.This compound consists of CuCl2 units linked together by ligand molecules, thus forming chains with distinct C2 symmetry perpendicular to the chain axis.The copper atom is co-ordinated in a distorted-tetrahedral geometry by two pyrazole nitrogens and two chloride atoms in cis positions.The sulphur atoms do not participate in the co-ordination, although molecular-mechanics calculations show that the ligand bddo is not sterically hindered to form tetradentate mononuclear chelates, i.e. with a MN2S2 chromophore.The structures of the other divalent metal halides were established as being very similar to that of the red modification.For semi-co-ordination of one or both tetrafluoroborates is indicated by the i.r. spectrum.Solid state 13C n.m.r. spectra of the copper(I) compounds indicate that the S atoms show significant shifts, suggesting co-ordination.In the thiocyanate and iodide compounds both thioether sulphurs co-ordinate in an identical manner, whereas in the chloride and bromide compounds they co-ordinate in a different manner.
