Tetra­carbonyl-2κ4C-[μ-5-methyl-1,1,3-triphenyl-2-(propan-2-yl)-2,4-di­aza-1,3-diphosphahexan-4-ido-1κN4:2κP1,P3](N,N,N′,N′-tetra­methyl­ethane-1,2-di­amine-1κ2N,N′)lithiummolybdenum

The title complex, [LiMo(C6H16N2)(C24H29N2P2)(CO)4], contains a distorted octa­hedrally coordinated molybdenum centre bearing a li­thia­ted P,P′-cis-chelating PNPN ligand, which results in a nearly planar four-membered metallacycle. The Li atom is coordinated by one equivalent tetra­methyl­ethylenedi­amine. In the crystal, mol­ecules are linked via weak C—H⋯O inter­actions, forming a chain along the b-axis direction.
