In the organic mol-ecule of the title hydrate, C11H15N3OS·H2O, {systematic name: 3-ethyl-1-{(E)-[1-(2-hy-droxy-phen-yl)ethyl-idene]amino}-thio-urea monohydrate}, a dihedral angle of 5.39 (2)° is formed between the hy-droxy-benzene ring and the non-H atoms comprising the side chain (r.m.s. deviation = 0.0625 Å), with the major deviation from planarity noted for the terminal ethyl group [the C-N-...

BACKGROUND Ticks are important vectors of human and animal pathogens. They are considered as main vectors for transmission of many viral, bacterial, rickettsial and parasitical pathogens. The aim of the present study was to find out species diversity of ticks, which infested the domestic ruminants in Zabol County, Eastern Iran in 2012. METHODS Ticks were selected randomly from sheep, goats, c...

The common feature of the mol-ecular structures of the title compounds, [Zn(C5H10NS2)2(C5H5NO)], (I), and [Zn(C4H8NOS2)2(C5H5NO)], (II), are NS4 donor sets derived from N-bound hy-droxy-pyridyl ligands and asymmetrically chelating di-thio-carbamate ligands. The resulting coordination geometries are highly distorted, being inter-mediate between square pyramidal and trigonal bipyramidal for both ...

Tumor-specific delayed hypersensitivity was transferred to peritoneal exÃodate cells obtained from unimmunized strain 2 guinea pigs after the peritoneal exÃodatecells were incubated with RNA-rich extracts from lymphoid tissues of syngeneic guinea pigs previously immunized to either of two antigenically distinct diethylnitrosamine-induced transplantable hepatomas. Tumor-specific delayed hypersen...

The title complex, [Ni(N(3))(2)(C(10)H(8)N(2))(CH(3)OH)(2)], lies on a twofold roation axis which runs through the Ni(II) ion and the mid-point of the bipyridine ligand. The Ni(II) ion is coordinated in a distorted octa-hedral environment by two azide ligands in a trans configuration. The methanol ligands are in a cis configuration and their hy-droxy groups form intra-molecular O-H⋯(N,N) hydrog...

In the title compound, C(29)H(25)N(3)O(3), the imine double bond has an E configuration. The dihedral angle between the hy-droxy-phenyl and benzene rings in the imine moiety is 26.95 (9)°, and the dihedral angle between the hy-droxy-phenyl and benzimidazole rings in the other moiety is 14.83 (9)°. These angles are probably limited to small values as a consequence of two strong intra-molecular O...
