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

ABSTRACT: 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(?-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].

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:In the title compound, C(15)H(15)N(5)O(4), a nitro-formazan derivative, the formazan unit is essentially planar with an r.m.s. deviation of 0.0204?(6)?Å and adopts a closed syn,s-cis configuration with an intra-molecular N-H?N hydrogen bond. The formazan plane makes dihedral angles of 4.32?(5) and 24.35?(5)° with the benzene rings. The dihedral angle between the formazan plane and the nitro group is 12.58?(8)°. In the crystal, C-H?O inter-actions connect the mol-ecules into an inversion dimer.

2-Meth-oxy-imino-2-{2-[(2-methyl-phen-oxy)meth-yl]phen-yl}ethanol.

Project description:In the title compound, C(17)H(19)NO(3), the dihedral angle between the benzene rings is 68.0 (1)°. The C-O-C-C torsion angle of the atoms joining these rings is 179.7 (2)°. The atoms of the methanol group were refined as disordered over two sets of sites with fixed occupancies of 0.86 and 0.14. The H atoms of the hy-droxy group in the major component are disordered over a further two sets of sites with equal occupancies. This is a necessary arrangement to allow for hydrogen bonding without unrealistic H⋯H contacts. In the crystal, O-H⋯N and O-H⋯O hydrogen bonds connect mol-ecules into chains along [001].

3-Meth-oxy-2-[(E)-(4-meth-oxy-phen-yl)imino-meth-yl]phenol.

Project description:The title compound, C(15)H(15)NO(3), adopts the enol-imine tautomeric form. The two rings are twisted with respect to each other, making a dihedral angle of 44.08 (5)°. The 3-methoxy-2-[(E)-(4-methoxyphenyl)-iminomethyl]phenol unit is almost planar, the largest deviation from the mean plane being 0.047 (2) Å. Such a planar conformation might be related to the occurrence of an intra-molecular O-H⋯N hydrogen bond. In the crystal, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into sheets parallel to (010). These sheets are inter-connected by weak C-H⋯π inter-actions.

An intra-molecular O-H?O hydrogen bond occurs in each mol-ecule. Inter-molecular C-H?O hydrogen bonds stabilize the crystal structure.
