Abstract
A new coordination compound of chromium (III) with
dimethyl-N-trichloroacetylamidophosphate
(L–=Cl3CC(O)NP(O)(OCH3)2) has been obtained. Based on IR data, the
bidentate coordination mode of the carbacylamidophosphate ligand is suggested.
The centrosymmetric binuclear complex [Cr2(L)4(μ2–OCH3)2]
has molecular structure according to X-ray
analysis. The phosphoramidic ligands are coordinated in a bidentate manner
via oxygen atoms of phosphoryl and carbonyl groups, and the coordination
polyhedra represent the cis-isomer. The coordination environment of the
central ion possesses a distorted octahedral geometry with c.n.=6. The
polyhedron (CrO6) comprises 4O from two bidentate phosphorylic ligands
and 2O from bridging methoxide ions.
