Summary
The synthesis of coordination compounds of formula M(viz)n(A)2 is described, where viz. =N-vinylimidazole, M = Mn, Fe, Co, Ni, Cu, Zn or Cd, A = ClO −4 , BF −4 or NO −3 , and n varies from 3 to 6, depending upon the particular combination of cation and anion. The compounds are easily prepared in ethanol from the hydrated metal(II) salts and the ligand and the products were characterized using i.r., ligand-field, far-i.r. and e.p.r. spectra in conjunction with x-ray powder diagrams and magnetic techniques. Octahedral cations [M(viz)6]2+ are formed in many cases, although square planar species Cu(viz)4(A)2 and tetrahedral species [M(viz)4]2+ for M = Co and Zn are also found.
Compared withN-alkylimidazole ligands, viz behaves differently in some cases, resulting in special effects in the crystal packing, and can be related to the quite rigid ligand structure. The “pyridine-type” N-atom of the imidazole ring appears to be coordinated; in all compounds no evidence is found for C=C double bond coordination.
