Tetracarbonyl[difluoromethylenebis(diisopropoxyphosphine-P)]molybdenum(0)

The title compound, [{(ⁱPrO)₂PCF₂P(OⁱPr)₂}Mo(CO)₄] or [Mo(C₁₃H₂₈F₂O₄P₂)(CO)₄], crystallizes without imposed symmetry. The four-membered ring is folded by 21.2 (1)° about the P...P axis. The Mo—P bonds are short [2.4351 (7) and 2.4445 (8) Å] and the P—C bonds long [1.889 (2) and 1.892 (3) Å] compared with systems lacking electronegative substituents.
