Tricarbon-yl(?-4',7-dimethoxy-iso-flavone)chromium(0).

ABSTRACT: The metal atom of the Cr(CO)(3) unit of the title compound, [Cr(C(17)H(14)O(4))(CO)(3)], is coordinated to the methoxy-phenyl ring of the isoflavone ligand; the Cr(CO)(3) unit exhibits a three-legged piano-stool conformation. The aromatic ring of the methoxy-phenyl group is twisted by 42.49?(9)° with respect to the ?-pyrone ring. In the fused-ring, the dihedral angle between the phenyl-ene and ?-pyrone rings is 3.08?(13)°.

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

Project description: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.

Racemic tricarbon-yl(?-7-meth-oxy-flavan)chromium(0).

Project description:IN THE TITLE COMPOUND [SYSTEMATIC NAME: tricarbonyl(?(6)-7-methoxy-2-phenyl-3,4-dihydro-2H-1-benzopyran)chromium(0)], [Cr(C(16)H(16)O(2))(CO)(3)], the Cr(CO)(3) unit is coordinated by the phenyl-ene ring of the flavan ligand, exhibiting a three-legged piano-stool conformation, with a point to plane distance of 1.750?(1)?Å.

The dihydro-pyran ring displays a distorted envelope configuration by displacement of the phenyl-bearing and the adjacent ring C atoms from the fused-ring system plane by 0.356?(2) and 0.402?(2)?Å, respectively.

Racemic tricarbon-yl[7-meth-oxy-2-(?-phen-yl)chromane]-chromium(0).

Project description:In the title compound, [Cr(C(16)H(16)O(2))(CO)(3)], the Cr(0) atom of the Cr(CO)(3) unit is coordinated to the phenyl ring of the flavan ligand in an ?(6) mode, with a normal arene-to-metal distance. The Cr(CO)(3) unit exhibits a three-legged piano-stool conformation, while the dihydro-pyran ring displays a distorted envelope configuration. The phenyl ring is twisted away from the fused ring system by 25.5?(2)°. The meth-oxy group is almost coplanar with the phenyl ring [C(Me)-O-C(ar)-C(ar) torsion angle = 8.46?(2)°]. The crystal packing is stabilized by inter-molecular C-H?O inter-actions.

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.

Tricarbon-yl[?-2-(methyl-diphenyl-phosphanium-yl)-1,3,4-triphenylcyclo-penta-dienyl]molybdenum(0).

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. The distance between the Mo(0) atom and the cyclo-penta-dienyl ring is 2.0616?(13)?Å.

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.
