cis-Dioxodichloro(diisopropyl (N,N-diethylcarbamyl)methylenephosphonate)molybdenum(VI), MoO/sub 2/Cl/sub 2/((i - C/sub 3/H/sub 7/O)/sub 2/P(O) - CH/sub 2/C(O)N(C/sub 2/H/sub 5/)/sub 2/), has been prepared from the addition of MoO/sub 2/Cl/sub 2/ to the phosphonate ligand in ethanol. The resulting complex has been characterized by infrared and /sup 1/H, /sup 13/C(/sup 1/H), and /sup 31/P(/sup 1/H) NMR spectroscopy and single-crystal X-ray diffraction analysis. The crystal parameters for the complex are presented. The structure was solved by heavy-atom techniques, and blocked least-squares refinement converged with R/sub F/ = 3.3% and R/sub wF/ = 3.4% for 3502 unique reflections with F greater than or equal to 5sigma(F). The structure contains monomeric units of the complex with the six-coordinate Mo atom having a pseudooctahedral coordination geometry. The carbamylmethylenephosphonate ligand is bonded to the Mo atom in a bidentate manner. Several important bond distances for molybdenum bonded to other elements are given.
