From an endophytic fungus, a close relative of Talaromyces sp., found in association with Cedrus deodara, four compounds including two new ones (2 and 4) were isolated and characterized. The structures of two compounds (1 and 4) were confirmed by X-ray crystallography. The compounds displayed a range of cytotoxicities against human cancer cell lines(More)
In the centrosymmetric title compound, [Cd(2)(C(13)H(12)NOS(2))(4)], pairs of dithio-carbamate ligands exhibit different structural functions. Each of the terminal ligands is bidentately coordinated to one Cd(II) atom and forms a planar four-membered CS(2)Cd chelate ring, whereas pairs of the tridentate bridging ligands link two neighbouring Cd(II) atoms,(More)
In the title complex, [Cd(C(6)H(11)N(2)S(2))(2)(C(5)H(5)N)(2)], the Cd(II) ion is hexa-coordinated by two N atoms from two pyridine ligands and by four S atoms from two dithio-carbamate ligands in a distorted octa-hedral geometry. The Cd(II) ion lies on a twofold axis. The piperazine ring is in chair conformation and its least-squares plane makes a dihedral(More)
In the title 1:1 co-crystal, C(10)H(7)BrN(4)S·C(7)H(5)BrO(2), the triazolothia-diazole system is approximately planar [with a maximum deviation of 0.030 (4) Å] and forms a dihedral angle of 8.6 (1)° with the bromo-phenyl ring. In the carb-oxy-lic acid mol-ecule, the carboxyl group is rotated by 6.4 (3)° out of the benzene ring plane. The crystal structure(More)
The title compound, C(22)H(23)BrN(4)O(3)S(2), crystallizes with two mol-ecules, A and B, in the asymmetric unit. In one of these, the meth-oxy group is disordered over two sets of sites in a 0.565 (9):0.435 (9) ratio. The benzene rings bridged by the sulfonamide group are tilted relative to each other by 37.4 (1) and 56.1 (1)° in mol-ecules A and B,(More)
In the title compound, C25H23N3O2, the central benzene ring makes dihedral angles of 77.14 (8) and 87.7 (2)° with the terminal benzene rings and an angle of 1.9 (1)° with the pyrazolone ring. The benzene ring and the N atom of the pyrazole ring bearing the phenyl substituent are disordered over two sets of sites with an occupancy ratio of 0.71 (2):0.29 (2).(More)
In the title mol-ecule, C(8)H(7)BrO(2), the carboxyl group is twisted by 76.2 (3)° from the benzene ring plane. In the crystal, mol-ecules are linked into inversion dimers through pairs of O-H⋯O hydrogen bonds. The dimers are further linked into layers parallel to the bc plane by weak C-H⋯O hydrogen bonds.
In the title compound, C(25)H(29)BrN(4)O(3)S(2), the benzene rings bridged by the sulfonamide group are tilted relative to each other by 63.9 (1)° and the dihedral angle between the sulfur-bridged pyrimidine and benzene rings is 64.9 (1)°. The mol-ecular conformation is stabilized by a weak intra-molecular π-π stacking inter-action between the pyrimidine(More)
In the title compound, C(18)H(18)ClN(5)O(3), the hydrazinecarboxamide N-N-C(O)-N unit is nearly planar [maximum deviation = 0.074 (2) Å] and is inclined at a dihedral angle of 57.43 (7)° with respect to the plane of the attached benzene ring. The chloro-phenyl group makes dihedral angles of 19.71 (7) and 34.07 (6)° with the pyrazole and benzene rings,(More)
