The complex [(PhCH2CH2O) 2PS2] 3Cr was synthesized and characterized by elemental analysis, IR, UV-Vis, thermogravimetric analysis and X-ray diffraction. The crystal belongs to the triclinic and P-1 space group. The unit cell parameters are: a = 1.39418 (3) nm, b = 1.40150 (3) nm, c = 1.47012 (3) nm and α = 76.3126 , β = 101.033 (3) °, γ = 78.7534 (17) °, V = 2.61241 (9) nm3, Dc = 1.353 Mg · m -3, Z = 2, F (000) = 1110, = 0.596 mm-1, S = 1.019, (Δ / σ) max = 0.001, R1 = 0.0512, wR2 = 0.1576 (I> 2σ (I)). The (PhCH2CH2O) 2PS2- in the complex is a bidentate ligand. The Cr atom coordinates with the six S atoms of the three ligands (PhCH2CH2O) 2PS2- to form a distorted octahedron with a Cr-S bond length of 0.24193 ( 9) ~ 0.24476 (9) nm.
