In the title compound, C15H15N3OS, the dihedral angle between the planes of the benzene and pyridine rings is 26.86 (9)°. Intra-molecular N-H⋯O and C-H⋯S hydrogen bonds both generate S(6) rings. The C=O and C=S bonds lie to opposite sides of the mol-ecule. In the crystal, inversion dimers linked by pairs of N-H⋯S hydrogen bonds generate R 2 (2)(8) loops.
In the title complex, [Ni(C(7)H(14)N(4)OS)(2)]Cl(2), the Ni(II) ion is six-coordinated in a distorted octa-hedral geometry by four N atoms from the two imine and two oxime groups, and two S atoms from the thione groups. Two chloride ions complete the asymmetric unit. In the crystal, mol-ecules are linked through N-H⋯Cl and O-H⋯Cl hydrogen bonds into an(More)
The asymmetric unit of the title compound, [Ni(C(6)H(12)N(4)OS)(2)]Cl(2), contains two independent Ni(II) complex cations and four chloride anions. Each Ni(II) ion is six-coordinated in a distorted octa-hedral geometry by four N atoms from the two imine and two oxime groups and two S atoms from the thione group. In the crystal, the cations and anions are(More)
The asymmetric unit of the title compound, [Ni(C(15)H(11)N(4)OS)(2)]·C(3)H(7)NO, contains one Ni(II) complex mol-ecule and one disordered dimethyl-formamide solvent mol-ecule. The Ni(II) ion is six-coordinated in a distorted octa-hedral geometry by two N, two O and two S atoms. An intra-molecular C-H⋯S hydrogen bond generates an S(6) ring motif. In the(More)
In the title benzimidazole mononuclear complex, [ZnCl(2)(C(13)H(11)N(3))], the Zn(II) ion is four-coordinated in a distorted tetra-hedral geometry by an imidazole N, an amino N and two Cl atoms. The dihedral angle between the benzimidazole and benzene rings is 9.57 (1)°. In the crystal, mol-ecules are linked by weak N-H⋯Cl hydrogen bonds into layers(More)
In the title mononuclear complex, [Zn(C(21)H(16)N(3)O)Cl], the Zn(II) ion is coordinated in a distorted tetra-hedral geometry by two benzimidazole N atoms and one phenolate O atom from the tridentate Schiff base ligand and a chloride ligand. The benzimidazole ring system forms dihedral angles of 26.68 (9) and 56.16 (9)° with the adjacent benzene ring and(More)
In the title solvated benzimidazole compound, C(20)H(15)N(3)O(2)·C(2)H(6)OS, both the benzimidazole fused-ring system and the complete dimethyl sulfoxide solvent mol-ecule are disordered over two sets of sites, in 0.750 (5):0.250 (5) and 0.882 (4):0.118 (4) ratios, respectively. The conformation of the pyrimidine ring is close to a half-chair for the major(More)
In the zwitterionic title compound, C(18)H(16)N(2)O(4)·H(2)O, the dihedral angle between the planes of the benzene and indole rings is 39.20 (8)°. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, inter-molecular hy-droxy and water O-H⋯O(carboxyl-ate) and N(+)-H⋯O(carboxyl-ate) and indole N-H⋯O(water) hydrogen bonds give a(More)
The title compound, 0.75C(15)H(14)N(2)O·0.25C(15)H(14)N(2)O, is a co-crystal of 2-methyl-6-(6-methyl-1H-benzimidazol-2-yl)phenol as the major component and 2-methyl-6-(5-methyl-1H-benz-imidazol-2-yl)phenol as the minor component. The refined site-occupancy ratio is 0.746 (4)/0.254 (4). The conformations of both components are identical except for that of(More)
The asymmetric unit of the title Schiff base complex, [Mn(C(36)H(46)N(2)O(2))Cl], comprises two crystallographically independent mol-ecules. The Mn(III) centre in each mol-ecule adopts a distorted square-pyramidal geometry. Each Mn(III) ion is coordinated by the N(2)O(2) atoms of the tetra-dentate Schiff base ligand forming the basal plane and the(More)
