Abstract

A series of Cr(III) complexes with dichloro-tetramorpholino-cyclophosphazatriene (L) as ligand was prepared. Dichloro-tetramorpholino-cyclophosphazatriene (L) reacts with chromium compounds (CrCl₃·6H₂O, K₃[Cr(NCS)₆], Cr₂(SO₄)₃·H₂O, and Cr(NO₃)₃·9H₂O) 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)Cl₃], [Cr₂L(OH₂)₂Cl₆], [Cr₃L₂(OH₂)₂Cl₈]Cl, K[CrL(SCN)₄], [CrL(OH₂)₃(SO₄)₄](SO ₄)_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, UV-VIS and EPR spectra, molar electrical conductivity and magnetic susceptibility measurements.
