Abstract

X-ray crystal structures of [Et3NH][{(CO)5Mo(P(OCH2CMe2CH2O)O)}2H], 3, and (CO)5Mo{μ-Ph2POPPh2}Mo(CO)5, 2, are reported. Crystallization of 3 occurs in P-1 space group with a = 9.6944(19) Å, b = 10.814(2) Å, c = 19.730(4) Å, α = 94.24(3)°, β = 92.23(3)°, γ = 113.47(3)°, Z = 4. Crystallization of 2 occurs in C2/c space group with a = 10.357(2) Å, b = 20.149(4) Å, c = 17.155(3) Å, α = 90°, β = 97.28(3)°, γ = 90°, Z = 8. Compound 2 is a bimetallic complex with a P–O–P bridging group containing bond distances similar to that of other complexes in which two metal centers are bridged by a single R2POPR2 ligand. Compound 3 contains intermolecular hydrogen bonded P–O–H–O–P linkages with bond distances comparable to those seen in similar structures with intramolecular hydrogen bonding suggesting that the distance is a function of the nature of the bond and not affected by the cis arrangement of the ligands about the metal center.
