ABSTRACT: In the title hydrated zwitterion, C11H13NO3S2·H2O, the N-C-C-C and C-C-C-S torsion angles in the side-chain are 171.06?(14) and 173.73?(12)°, respectively. In the crystal, inversion-related mol-ecules are ?-stacked with an inter-planar separation of 3.3847?(2)?Å. O-H?O hydrogen bonds link inversion-related mol-ecules with a pair of water mol-ecules to form R 4 (2)(8) rings. The closest S?S contact is 3.4051?(15)?Å between inversion-related mol-ecules.

Crystal structures of 2-amino-4,4,7,7-tetra-methyl-4,5,6,7-tetra-hydro-1,3-benzo-thia-zol-3-ium benzoate and 2-amino-4,4,7,7-tetra-methyl-4,5,6,7-tetra-hydro-1,3-benzo-thia-zol-3-ium picrate.

Project description:In both 2-amino-4,4,7,7-tetra-methyl-4,5,6,7-tetra-hydro-1,3- benzo-thia-zol-3-ium benzoate, C11H19N2S+·C7H5O2-, (I), and 2-amino-4,4,7,7-tetra-methyl-4,5,6,7-tetra-hydro-1,3-benzo-thia-zol-3-ium picrate (2,4,6-tri-nitro-phenolate), C11H19N2S+·C6H2N3O7-, (II), the cations are conformationally chiral as the six-membered rings adopt half-chair conformations, which are disordered over two sets of atomic sites giving approximately enanti-omeric disorder. For both cations, the bond lengths indicate delocalization of the positive charge comparable to that in an amidinium cation. The bond lengths in the picrate anion in (II) are consistent with extensive delocalization of the negative charge into the ring and onto the nitro groups, in two of which the O atoms are disordered over two sets of sites. In (I), the ionic components are linked by N-H?O hydrogen bonds to form a chain of rings, and in (II), the N-H?O hydrogen bonds link the components into centrosymmetric four-ion aggregates containing seven hydrogen bonded rings of four different types.

3-(4-Meth-oxy-phen-yl)-1,3-selenazolo[2,3-b][1,3]benzo-thia-zol-4-ium hydrogen sulfate.

Project description:The title compound, C16H12NOSSe(+)·HSO4 (-), was obtained from a mixture of 3-(4-meth-oxy-phen-yl)[1,3]selenazolo[2,3-b][1,3]benzo-thia-zol-4-ium chloride and potassium hydrogen sulfate. In the cation, the benzene ring is twisted by 71.62?(7)° from the tricycle mean plane. In the crystal, O-H?O hydrogen bonds link the anions into chains along [100]. The anions in adjacent chains are linked via weak C-H?O hydrogen bonds. The crystal packing exhibits short inter-molecular contacts between the chalcogen unit and the O atoms: Se?O(anion) 2.713?(3), Se?O(cation) 2.987?(3) and S?O(anion) 2.958?(3)?Å.

2-(1,3-Thia-zol-4-yl)benzimidazolium nitrate monohydrate.

Project description:In the title compound, C(10)H(8)N(3)S(+)·NO(3) (-)·H(2)O, one of the N atoms of the benzimidazole unit is protonated, unlike than that in the thia-zole group. This protonation leads to equalization of the bond angles at the two N atoms of the benzimidazole group. The benzimidazole and thia-zole systems are almost coplanar, forming a dihedral angle of 0.5?(2)°. In the crystal, the nitrate anion and water mol-ecule bridge the thia-bendazolium cations through N-H?O and O-H?O hydrogen bonds, leading to a supra-molecular network based on an infinite one-dimensional chain using [001] as base vector.

Bis[2-(1,3-benzo-thia-zol-2-yl)phenyl-?(2) C (1),N][1,3-bis-(4-bromo-phen-yl)propane-1,3-dionato-?(2) O,O']iridium(III).

Project description:The title complex, [Ir(C15H9Br2O2)(C13H8NS)2], lies about a crystallographic twofold rotation axis passing through the Ir(III) atom and the central C atom of the bis-(bromo-phen-yl)propane-1,3-dionate ligand. The Ir(III) atom adopts a distorted octa-hedral geometry coordinated by two N atoms in the axial positions, and two C and two O atoms in the equatorial plane. The dihedral angle between the two thia-zole ring systems in the complex is 77.45?(10)°.

2-(6-Bromo-benzo[d]thia-zol-2-yl)-5,5-di-methyl-thia-zol-4(5H)-one.

Project description:The title compound, C12H9BrN2OS2, was obtained by reacting 6-bromo-benzo[d]thia-zole-2-carbo-nitrile in iso-propanol with ethyl 2-mercapto-2-methyl-propano-ate at reflux temperature for several hours. The resulting di-methyl-oxyluciferin derivative shows partial double-bond character of the carbon-carbon bond between the two heterocyclic moieties [C-C = 1.461?(3)?Å]. This double bond restricts rotation around this C-C axis, therefore leading to an almost planar mol-ecular structure [N-C-C-S torsion angle = 9.7?(3)°]. The five-membered thiazoline ring is not completely planar as a result of the bulky S atom [C-S-C-C torsion angle = 5.17?(12)°].
