In the title compound, C(26)H(28)N(4) (2+)·2PF(6) (-), the complete cation is generated by a crystallographic twofold axis. The benz-imidazole ring is almost planar (r.m.s. deviation = 0.0207 Å) and makes dihedral angles of 50.12 (2)° with its symmetry-related component and 65.81 (2)° with the central benzene ring. In the crystal, mol-ecules are linked into(More)
In the asymmetric unit of the title complex, [Ni(C16H14N3OS)2], the nickel ion is tetra-coordinated in a distorted square-planar geometry by two independent mol-ecules of the ligand which act as mononegative bidentate N,S-donors and form two five-membered chelate rings. The ligands are in trans (E) conformations with respect to the C=N bonds. The close(More)
A series of complexes of the type LAuCl where L = tris(p-tolylarsane), tris(m-tolylarsane), bis(diphenylarsano)ethane, and tris(naphthyl)arsane have been synthesized. All of the new complexes, 1-4, have been fully characterized by means of ¹H NMR and ¹³C NMR spectroscopy and single crystal X-ray crystallography. The structures of complexes 1-4 have been(More)
Two new series of aurone compounds were synthesized via an oxidative cyclization reaction of 2′-hydroxy-chalcones. Series (A) consists of 1a–3a aurones with different substitutions on a B-ring at position 4′, and series (B) is made up of 1b–3b aurones that have different substitutions at position 2′ of a B-ring. Structures of the synthesized compounds were(More)
The title compounds, C20H19NO3, (1), and C20H17Cl2NO, (2), are the 3-hy-droxy-benzyl-idene and 2-chloro-benzyl-idene derivatives, respectively, of curcumin [systematic name: (1E,6E)-1,7-bis-(4-hy-droxy-3-meth-oxy-phen-yl)-1,6-hepta-diene-3,5-dione]. The dihedral angles between the benzene rings in each compound are 21.07 (6)° for (1) and 13.4 (3)° for (2).(More)
The asymmetric unit of the title compound, [Ru3(C19H17P)(C25H22P2)(CO)9], consists of two independent mol-ecules. The bis-(di-phenyl-phosphan-yl)methane ligand bridges an Ru-Ru bond and the benzyl-diphenyl-phosphane ligand binds to the third Ru atom. The Ru-Ru bond cis to the benzyl-diphenyl-phosphane ligand is the longest of the three Ru-Ru bonds in both(More)
In the title compound, [SbBr(C10H7)2], the Sb(III) atom has a distorted trigonal-pyramidal coordination geometry and the planes of the two naphthalene ring systems make a dihedral angle of 80.26 (18)°. An intra-molecular C-H⋯Br hydrogen bond forms an S(5) ring motif. In the crystal, weak C-H⋯Br inter-actions link the mol-ecules into helical chains along the(More)
The mol-ecular structure of the title compound, C12H19NO5, may be visualized as made up of two nearly perpendicular planes [dihedral angle = 87.39 (12)°] and its crystal structure is a good example of C-H⋯O inter-actions assuming significance in optimizing supra-molecular aggregation in crystals in a mol-ecule which is severely imbalanced in terms of donors(More)
The asymmetric unit of the title compound, C22H18N4O2S2, contains two mol-ecules. In one of them, the dihedral angles between the central benzene ring and the phenyl rings are 16.97 (8) and 20.97 (8)°, while the phenyl rings make a dihedral angle of 37.87 (8)°. In the other mol-ecule, the corresponding values are 34.92 (7), 53.90 (7) and 60.68 (8)°,(More)
In the title compound, C(24)H(25)N(3)O(5), the eth-oxy group is disordered over two orientations in a 0.853 (14):0.147 (14) ratio. The benzimadazole ring system (r.m.s. deviation = 0.016 Å) makes a dihedral angle of 35.47 (7)° with the attached benzene ring. The pyrrolidine ring adopts an envelope conformation with a methyl-ene C atom as the flap. In the(More)
