7-Di-ethyl-amino-3-{(E)-4-[(E)-2-(pyridin-4-yl)ethen-yl]styr-yl}-2H-chromen-2-one.

ABSTRACT: In the title coumarin derivative, C28H26N2O2, the coumarin unit is approximately planar, with a maximum deviation of 0.048?(3)?Å. The central benzene ring is oriented at dihedral angles of 30.15?(14) and 10.51?(11)°, respectively, to the pyridine ring and coumarin ring system. In the crystal, weak C-H?O and C-H?N hydrogen bonds and weak C-H?? inter-actions link the mol-ecules into a three-dimensional supra-molecular architecture.

In the crystal, weak C-H⋯O and C-H⋯N hydrogen bonds and weak C-H⋯π inter-actions link the mol-ecules into a three-dimensional supra-molecular architecture. ...[more]

Project description:In the title compound, C18H22N2O4S2, the 2H-chromene ring system is essentially planar (r.m.s. deviation = 0.012?Å).

Crystal structures of two stilbazole derivatives: bis-{(E)-4-[4-(di-ethyl-amino)-styr-yl]-1-methyl-pyridin-1-ium} tetra-iodido-cadmium(II) and (E)-4-[4-(di-ethyl-amino)-styr-yl]-1-methyl-pyridin-1-ium 4-meth-oxy-benzene-sulfonate monohydrate.

Project description:The title mol-ecular salts, (C18H23N2)2[CdI4], (I), and C18H23N2 +·C7H7O4S-·H2O, (II), are stilbazole, or 4-styryl-pyridine, derivatives. The cation, (E)-4-[4-(di-ethyl-amino)-styr-yl]-1-methyl-pyridin-1-ium, has a methyl group attached to pyridine ring and a diethyl amine group attached to the benzene ring. The asymmetric unit of salt (I), comprises one cationic mol-ecule and half a CdI4 dianion. The Cd atom is situated on a twofold rotation axis and has a slightly distorted tetra-hedral coordination sphere. In (II), the anion consists of a 4-meth-oxy-benzene-sulfonate and it crystallizes as a monohydrate. In both salts, the cations adopt an E configuration with respect to the C=C bond and the pyridine and benzene rings are inclined to each other by 10.7 (4)° in (I) and 4.6 (2)° in (II). In the crystals of both salts, the packing is consolidated by offset π-π stacking inter-actions involving the pyridinium and benzene rings, with centroid-centroid distances of 3.627 (4) Å in (I) and 3.614 (3) Å in (II). In the crystal of (II), a pair of 4-meth-oxy-benzene-sulfonate anions are bridged by Owater-H⋯Osulfonate hydrogen bonds, forming loops with an R 2 4(8) motif. These four-membered units are then linked to the cations by a number of C-H⋯O hydrogen bonds, forming slabs lying parallel to the ab plane.

In addition, C-H?? and ?-? inter-actions [centroid-centroid distances = 3.950?(3)-4.024?(3)?Å] provide additional stability to the inter-layer regions in the lattice.

Project description:The title compound, C(12)H(7)ClN(2)O(2)S, crystallizes with two mol-ecules in the asymmetric unit.

(E)-2-[4-(Di-ethyl-amino)-styr-yl]-1-methyl-quinolinium 4-fluoro-benzene-sulfonate monohydrate.

Project description:In the title hydrated molecular salt, C22H25N2 (+)·C6H4FO3S(-)·H2O, the cation displays whole mol-ecule disorder over two sets of sites in a 0.780?(5):0.220?(5) ratio. The quinolinium ring system is essentially planar, with r.m.s. deviations of 0.0162 and 0.0381?Å for the major and minor disorder components, respectively. The dihedral angles between the mean plane of the quinolinium ring system and the benzene ring are 5.1?(3) and 7.7?(11)°, respectively, for the major and minor components in the cation. In the crystal, cations, anions and water mol-ecules are linked into chains along [010] by O-H?O hydrogen bonds and are further connected into a three-dimensional network by weak C-H?O and C-H?F inter-actions. In addition, ?-? inter-actions with centroid-centroid distances of 3.634?(3), 3.702?(5) and 3.838?(5)?Å are observed.
