Résumé
A series of Cr(III) complexes with dichloro-tetramorpholino-cyclophosphazatriene (L) as ligand was prepared. Dichloro-tetramorpholino-cyclophosphazatriene (L) reacts with chromium compounds (CrCl3 . 6H(2)O, K-3[Cr(NCS)(6)], Cr-2(SO4)(3). H2O, and Cr(NO3)(3). 9H(2)O) in methanolic solutions for the corresponding molar ratios of 1:1, 1:2, and 2:3. The general formulas of the obtained complexes are: [CrL(OH2)Cl-3], [Cr2L(OH2)(2)Cl-6], [Cr3L2(OH2)(2)Cl-8]Cl, K[CrL(SCN)(4)], [CrL(OH2)(3)(SO4)(1/2)[(Cr2L(OH2)(6)(SO4)(2)](SO4), [Cr3L2(OH2)(6)(SO4)(4)](SO4)(1/2), [CrL(OH2)(2)(NO3)(2)](NO3), [Cr2L(OH2)(4)(NO3)(4)](NO3)(2), [Cr3L2(OH2)(4)(NO3)(6)](NO3)(3). The complexes were characterized by means of elementar chemical analysis, IR, W-VIS and EPR spectra, molar electrical conductivity and magnetic susceptibility measurements.
