heal.abstract	The new ligands 1,4-diformylbenzene bishydrazone (DFBH) and 1,4-diacetylbenzene bishydrazone (DABH) have been prepared. DFBH forms complexes with transition metal(II) ions of types MX2(DFBH) (M = Co, Ni, Mn, Zn or Cd, X = Cl; M = Co or Ni, X = SCN; M = Ni, X = Br) and MX2(DFBH)2 (M = Co, Ni, Mn, Zn, Cd or Hg, X = Cl; M = Ni or Mn, X = Br). DABH forms complexes of types MX2(DABH)2 (M = Co, Ni or Zn, X = Cl or Br; M = Co or Ni, X = Cl, Br or SCN) and MX2(DABH)3 (M = Co, X = Br or SCN; N = Ni X = Cl or SCN; M = Zn, X = Cl, Br or SCN). Electronic spectra, magnetic moments and IR spectra have been used to deduce probable structures of the complexes. All contain six co-ordinated metals in high-spin configurations except ZnCl2(DFBH) and possibly CdCl2(DFBH) which are tetrahedral. The reactions between cobalt(II) halides and DABH in acetone yield the tetrahedral complexes CoX2 (DABAZ), where DABAZ = the acetone azine of 1,4-diacetylbenzene hydrazone. © 1987.	en
