Tricarbon-yl[N,N',N''-tris-(2,6-diisopropyl-phen-yl)guanidine]molybdenum(0).

ABSTRACT: In the title compound, [Mo(C(37)H(53)N(3))(CO)(3)], the Mo atom to ring-centroid distance in the ?(6)-coordinated tricarbonyl-molybdenum group is 1.958?(1)?Å. The three C O groups are pseudo-octa-hedrally disposed with C-Mo-C angles ranging from 80.7?(1) to 87.4?(1)°. The two uncoordinated 2,6-diisopropyl-phenyl-substituted benzene rings form dihedral angles of 75.96?(8) and 78.01?(9)° with the mean plane of the guanidine group. The coordinated benzene ring is in a slight sofa conformation with the N-substituted C atom and the bonded N atom dispaced by 0.090?(3) and 0.458?(4)?Å, respectively, from the mean plane of the remaining ring atoms. In the crystal, despite there being two N-H donor groups, no conventional hydrogen bonds are present. This may be because of the steric effects of the bulky diisopropyl-phenyl groups.
