3-[2-(Triphenyl-phosphanyl-idene)acet-yl]-2H-chromen-2-one.

ABSTRACT: In the title compound, C(29)H(21)O(3)P, a coumarin-substitued ylid, the P atom is linked to three benzene rings and a planar coumarin moiety via a methyl-enecarbonyl group. The bond lengths in the P=C-C=O fragment clearly indicate a delocalized system involving the olefinic and carbonyl bonds. The mol-ecular structure is stabilized by an intra-molecular C-H?O inter-action that results in an S7 graph-set ring motif. In the crystal, mol-ecules are linked into a three-dimensional framework by C-H?O hydrogen bonds.

(E)-3-(2-{2-[1-(3-Hy-droxy-phen-yl)ethyl-idene]hydrazin-yl}-1,3-thia-zol-4-yl)-2H-chromen-2-one.

Project description:In the title compound, C(20)H(15)N(3)O(3)S, the thia-zole ring is approximately planar, with a maximum deviation of 0.003?(1)?Å, and makes dihedral angles of 7.44?(6) and 1.88?(6)° with the hy-droxy-substituted phenyl ring and the pyran ring, respectively. The hydroxyl group is disordered over two sets of sites, with an occupancy ratio of 0.567?(3):0.433?(3). In the crystal, the major disorder component mol-ecules are connected via bifurcated (three-centre) O-H?O and C-H?O hydrogen bonds, generating R(1) (2)(6) motifs and resulting in supra-molecular chains along the a axis. In the minor occupancy component, however, mol-ecules are connected via C-H?O hydrogen bonds, forming supra-molecular chains along the b axis. Furthermore, the crystal structure is stabilized by ?-? inter-actions between the thia-zole rings [centroid-centroid distance = 3.5476?(7)?Å].
