S-5-Amino-2-(dimethyl-ammonio)phenyl sulfothio-ate.

ABSTRACT: The title compound, C(8)H(12)N(2)O(3)S(2), has been isolated as a by-product in the synthesis of methyl-ene blue dye. The compound crystallizes with four independent mol-ecules in the unit cell (Z'= 4). The zwitterionic form of the mol-ecule was established on the basis of the hydrogen atom located at the dimethyl-amino group. The crystal structure is dominated by inter-molecular hydrogen bonds of the N-H?O type formed between amino and ammonio N-H groups and O atoms from the sulfothio-ate group. There are in addition two weak inter-molecular N-H?N inter-actions and some non-conventional C-H?O hydrogen bonds.

S-2-Amino-5-(dimethyl-ammonio)phenyl sulfothio-ate.

Project description:The title compound, C(8)H(12)N(2)O(3)S(2), has been isolated as an inter-mediate in the synthesis of methyl-ene blue dye, the best known phenothia-zine dye, and structurally characterized as a zwitterion. The crystal structure is dominated by inter-molecular N-H?O hydrogen bonds between the amine and sulfothio-ate groups, with graph-set motif C(9)R(2) (2)(8), involving anti-parallel chains and a centrosymmetric eight-membered ring. A hydrogen bond with graph-set motif R(2) (2)(14) between the ammonium and sulfothio-ate groups completes the two-dimensional network in the ab plane. Inter-molecular C-H?O hydrogen bonds are also present in the crystal.

Hydrogen 4-ammonio-phenyl-phospho-n-ate.

Project description:The title compound, C(6)H(8)NO(3)P, is isostructural with p-arsanilic acid. It exists as the zwitterion H(3)N(+)C(6)H(4)PO(3)H(-). In the crystal, mol-ecules are linked by O-H⋯O and N-H⋯O hydrogen-bond bridges, giving a three-dimensional network structure. The strongest hydrogen bonds are formed between adjacent PO(3)H groups with O⋯O distances of 2.577 (2) Å.

2-(Dimethyl-amino-meth-yl)phenyl phenyl telluride.

Project description:The title compound, C(15)H(17)NTe, is a heteroleptic Te, N-bidentate ligand having a short Te?N contact [2.8079?(16)?Å] involving a secondary bonding inter-action between the amino N and Te(II) atoms. The Te-C bond [2.136?(2)?Å] trans to the amino group is slightly elongated compared to the other Te-C bond [2.1242?(18)?Å] due to the hypervalent inter-action. The bond angle for the trans N-Te-C atoms [164.92?(6)°] deviates significantly from linearity.

(E)-Ethyl 2-anilino-5-[3-(dimethyl-amino)-acrylo-yl]-4-phenyl-thio-phene-3-carboxyl-ate.

Project description:In the title compound, C24H24N2O3S, the phenyl rings form dihedral angles of 55.65?(11) and 79.60?(11)° with the plane of the thio-phene ring. The mol-ecular conformation is stabilized by an intra-molecular N-H?O hydrogen bond, generating an S(6) ring motif. In the crystal, centrosymmetrically related mol-ecules are linked into dimers by two pairs of C-H?O inter-actions.

4-(Dimethyl-amino)phenyl ethynyl telluride.

Project description:The title compound, C(10)H(11)NTe, is the first organyl ethynyl telluride, R-Te-C C-H, to be structurally characterized. In the L-shaped mol-ecule, the aryl moiety, viz. Me(2)NC(6)H(4)Te, is almost perpendicular to the Te-C C-H fragment. The Te-Csp(2) bond [2.115 (3) Å] is significantly longer than the Te-Csp bond [2.041 (4) Å]. The Te-C C group is approximately linear [Te-C-C = 178.5 (4)° and C C = 1.161 (5) Å], while the coordination at the Te atom is angular [C-Te-C = 95.92 (14)°]. In the crystal structure, there are Csp-H⋯N hydrogen bonds which are perpendicular to the CNMe(2) group; the N atom displays some degree of pyramidalization. Centrosymmetrically related pairs of mol-ecules are linked by Te⋯π(ar-yl) inter-actions, with Te⋯Cg = 3.683 (4) Å and Csp-Te⋯Cg = 159.1 (2)° (Cg is the centroid of the benzene ring). These inter-actions lead to the formation of zigzag ribbons which run along c and are approximately parallel to (110).

Weak C-H⋯π inter-actions are also observed.

Project description:In the title compound, C27H22N2O4, the two indole ring systems are approximately perpendicular to each other, with a dihedral angle of 84.5?(5)° between their planes; the benzene ring is twisted with respect to the two indole ring systems at angles of 78.5?(5) and 86.5?(3)°.

Project description:The title mol-ecule, C(19)H(23)NO(4), was synthesized by the reaction of benzaldehyde, ethyl acetoacetate and NH(4)HCO(3).

Project description:In the title compound, C(17)H(17)NO(4), the dihedral angle between the benzene and pyridine rings is 75.51?(4)°.

The crystal structure is stabilized by weak inter-molecular C-H?O and C-H?N inter-actions.
