Tricarbon-yl(?-flavone)chromium(0).

ABSTRACT: In the title compound, [Cr(C(15)H(10)O(2))(CO)(3)], the Cr(CO)(3) unit exhibits a three-legged piano-stool conformation. The chromium metal centre is coordinated by the phenyl ring of the flavone ligand [Cr-(phenyl centroid) distance = 1.709?(1)?Å]. The ligand is approximately planar, the dihedral angles between the ?-pyrone ring and the phenyl ring and between the ?-pyrone and the phenyl-ene ring being 2.91?(5) and 3.90?(5)°, respectively. The mol-ecular packing shows ?-? stacking between the flavone ligands of neighbouring mol-ecules.

In the title compound, [Cr(C(15)H(10)O(2))(CO)(3)], the Cr(CO)(3) unit exhibits a three-legged piano-stool conformation. The chromium metal centre is coordinated by the phenyl ring of the flavone ligand [Cr-(phenyl centroid) distance = 1.709 (1) Å]. The ligand is approximately planar, the dihedral angles between the γ-pyrone ring and the phenyl ring and between the γ-pyrone and the phenyl-ene ring being 2.91 (5) and 3.90 (5)°, respectively. The mol-ecular packing shows π-π stacking between the f ...[more]

Tricarbon-yl(2-methyl-2-?-phenyl-1,3-dioxolane)chromium(0).

Project description:The structure of the title compound, [Cr(C(10)H(12)O(2))(CO)(3)], is presented. The distorted piano-stool geometry features an off-center Cr(CO)(3) fragment which reduces contact with the dioxolane ring. The dioxolane ring, in twisted conformation, is syn-oriented towards the Cr(CO)(3) moiety.

Project description:The title compound, [Mo(C(36)H(29)P)(CO)(3)], contains an Mo(0) atom with a typical piano-stool coordination defined by the phospho-nium cyclo-penta-dienylide ligand ?(5)-1-(methyl-diphenyl-phosphanium-yl)-2,3,5-triphenyl-2,4-cyclo-penta-dien-1-yl and by three carbonyl groups.

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

Project description: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.
