Association of Quaterpyridine Complex Cations with Polyanionometallates
Résumé
Reactions in CH3CN:CH2Cl2 (2:1) under Ar of the dimethyl-quaterpyridine ligand C22H18N4 (L) with Mn(ClO4)2, Fe(BF4)2, CoCl2, Co(NO3)2, Zn(NO3)2, Cd(CH3COO)2 and HgCl2 give complexes of the type [ML(H2O)mXn]2[MXp], where X denotes the initial counterions, with m=1, n=1, p=4 or m=2, n=0, p=6. The complexes have been characterized by spectroscopic techniques and elemental analysis. The solid state structures of two forms of the CoCl2 complex have been established by X-ray crystallography, enabling an analysis of the interactions occurring in crystals of this type.
