1-(4-Chloro-phenyl)-2-[tris-(4-methyl-phenyl)-?(5)-phosphanyl-idene]butane-1,3-dione.

ABSTRACT: In the title ylide, C(31)H(28)ClO(2)P [common name ?-acetyl-?-p-chloro-benzoyl-methyl-enetri(p-tol-yl)phospho-rane], the dihedral angle between the 4-chloro-phenyl ring and that of the ylide moiety is 66.15?(10)°. The geometry around the P atom is slightly distorted tetra-hedral [angle range = 105.22?(8)-115.52?(9)°] and the carbonyl O atoms are syn-oriented with respect to the P atom. The ylide group is close to planar [maximum deviation from the least-squares plane = 0.006?(2)?Å] and the P-C, C-C and C=O bond lengths are consistent with electron delocalization involving the O atoms.

In the title ylide, C(31)H(28)ClO(2)P [common name α-acetyl-α-p-chloro-benzoyl-methyl-enetri(p-tol-yl)phospho-rane], the dihedral angle between the 4-chloro-phenyl ring and that of the ylide moiety is 66.15 (10)°. The geometry around the P atom is slightly distorted tetra-hedral [angle range = 105.22 (8)-115.52 (9)°] and the carbonyl O atoms are syn-oriented with respect to the P atom.

4-[(4-Chloro-phen-yl)(hy-droxy)methyl-idene]isochromane-1,3-dione.

Project description:In the title compound, C(16)H(9)ClO(4), the six-membered heterocyclic ring adopts a screw-boat conformation. The benzene rings are oriented to each other at a dihedral angle of 59.26 (9)°. The mol-ecular structure exhibits a ring motif, viz. S(6), owing to an intra-molecular O-H⋯O hydrogen bond. The presence of C-H⋯O contacts generates an infinite chain along [001]. Also present are π-π stacking inter-actions between neighbouring isochromanedione benzene rings [centroid-centroid distance = 3.746 (1) Å], and C-O⋯π inter-actions [O⋯centroid = 3.934 (2) Å].

Crystal structure of 2,2-di-chloro-1-(piperidin-1-yl)butane-1,3-dione.

Project description:In the title compound, C9H13Cl2NO2, the piperidine ring shows a chair conformation and the O-C-C-O torsion angle between the carbonyl groups is 183.6 (4)°. In the crystal, mol-ecules are linked into an infinite layer along the ab plane by a bifurcated C-H?O hydrogen bond between the carbonyl O atom adjacent to the methyl group and one of the methyl-ene groups next to nitro-gen and an additional hydrogen bond of the C-H?Cl type. These layers are connected into a three-dimensional supra-molecular arrangement by O?Cl contacts [2.8979?(12) and 3.1300?(12)?Å].

Project description:The mol-ecular structure of the title compound, C(21)H(15)ClN(2)O(2), features one strong intra-molecular N-H?O resonance-assisted hydrogen bond (RAHB). In the crystal, mol-ecules form inversion-related dimers via pairs of weak inter-molecular N-H?O contacts. These dimers are further stabilized via three weak C-H?O contacts, developing the three-dimensional structure.

3-Chloro-1-methyl-4-[2-(3-phenyl-allyl-idene)hydrazinyl-idene]-3,4-dihydro-1H-2?(6),1-benzothia-zine-2,2-dione.

Project description:In the title compound, C(18)H(16)ClN(3)O(2)S, the dihedral angle between the aromatic rings is 4.81?(2)° and the alkyl chain takes on an extended conformation [N-C-C-C = 179.2?(4)°]. The conformation of the thia-zine ring is an envelope, with the S atom displaced by -0.805?(3)?Å from the mean plane of the other five atoms (r.m.s. deviation = 0.046?Å). The Cl atom is an axial conformation and is displaced by 1.761?(4)?Å from the thia-zine ring plane. In the crystal, inversion dimers linked by pairs of C-H?O inter-actions generate R(2) (2)(20) loops and further C-H?O hydrogen bonds link the dimers into (001) sheets. Weak aromatic ?-? stacking inter-actions [centroid-centroid separations = 3.870?(3) and 3.883?(3)?Å] are also observed.

(E)-2,2-Dimethyl-5-(3-phenyl-allyl-idene)-1,3-dioxane-4,6-dione.

Project description:The title compound, C(15)H(14)O(4), was prepared by the reaction of 2,2-dimethyl-1,3-dioxane-4,6-dione and (Z)-3-phenyl-acryl-aldehyde in ethanol.

With the exception of the flap atom and the methyl group C atoms, all other non-H atoms are essentially planar, with an r.m.s. deviation of 0.067?(1)?Å. The crystal structure is stabilized by weak inter-molecular C-H?O hydrogen bonds.
