In the title mol-ecule, C(10)H(11)NO(5), the methyl C atom deviates by 0.830 (6) Å from the mean plane of the remaining non-H atoms. In the crystal, weak C-H⋯O hydrogen bonds link the mol-ecules into layers parallel to the bc plane.

In the title compound, C(8)H(6)BrCl(3)O, there is a weak intra-molecular C-H⋯Cl hydrogen bond involving the O bound methylene group. Intermolecular Cl⋯Cl contacts [3.482 (2) Å] are present in the crystal structure.

Telematics applications play an essential role in the dissemination of environmental information and environmental measures. This contribution gives an overview of the applications of environment telematics in Europe as a result of two projects which were performed on an international level. The analysis covers the situation in EC countries as well as in CEE countries, with an emphasis on regio...

The mol-ecule of the title compound, C(5)H(9)NO(3), is essentially planar [the maximum deviation for a non-H atom from the mean plane is 0.021 (3) Å] due to the π-conjugation of the hydroxy-imino and carbonyl groups, which are trans to each other; ab initio calculations in vacuo at the DFT (B3LYP/6-311G**++) level of theory confirmed that E conformer is indeed the lowest in energy. The packing ...

The triphenyl-methyl group in the title compound, C(28)H(23)IO(2)S, has the methine carbon slightly flattened out [ΣC(phen-yl)-C-C(phen-yl) = 332.8 (6) °]. The -C-O-C-C-S- chain connecting the triphenyl-methyl group and the aromatic ring adopts an extended zigzag conformation, these five atoms being approximately co-planar (r.m.s. deviation 0.260 Å).

The title compound, C(6)H(11)N(3)O(2)S, consists of a roughly planar mol-ecule (r.m.s deviation from planarity = 0.077 Å for the non-H atoms) and has the S atom in an anti position to the imine N atom. This N atom is the acceptor of a strongly bent inter-nal N-H⋯N hydrogen bond donated by the amino group. In the crystal, mol-ecules are arranged in undulating layers parallel to (010). The mol-ec...

experimental results of dielectric investigations for binary mixtures of 2, 3-butanediol, 2, 3-bd, in2-ethyl-1-hexanol, 2eh, were reported for various mole fractions and temperatures (298.2-308.2) kand they were used to calculate dielectric parameters such as kirkwood correlation factor, excesspermittivity and bruggeman parameter. these parameters were used to carry out temperaturedependent die...
