In the title compound, C(16)H(13)IN(2), the benzene ring of the tetra-hydro-isoquinoline moiety makes a dihedral angle of 45.02 (9)° with the benzene ring of the 4-iodo-phenyl fragment. The N atom and the adjacent unsubstituted C atom of the tetra-hydro-isoquinoline unit are displaced by 0.294 (2) and 0.441 (3) Å, respectively, from the plane through the remaining eight C atoms. In the crystal,...

A new model to deal with the short-term generation scheduling problem for hydrothermal systems is proposed. Using genetic algorithms (GAs), the model handles simultaneously the subproblems of short-term hydrothermal coordination, unit commitment, and economic load dispatch. Considering a scheduling horizon period of a week, hourly generation schedules are obtained for each of both hydro and the...

The asymmetric unit of the title compound, C44H44N2O6, contains two independent mol-ecules with similar conformations. The di-hydro-naphthalene ring systems are approximately planar [maximum deviations = 0.036 (2), 0.128 (2), 0.0.24 (2) and 0.075 (2) Å]. The dihedral angle between two di-hydro-naphthalene ring systems is 83.37 (4)° in one mol-ecule and 88.99 (4)° in the other. The carbonyl O at...

THE CRYSTAL STRUCTURE OF THE TITLE COMPOUND (SYSTEMATIC NAME: 2-amino-1-methyl-4-oxo-4,5-dihydro-1H-imidazol-3-ium 3-phenyl-prop-2-enoate), C(4)H(8)N(3)O(+)·C(9)H(7)O(2) (-), is stabilized by N-H⋯O hydrogen bonding. Cations are linked to anions to form ion pairs with an R(2) (2)(8) ring motif. These ion pairs are connected through a C(2) (2)(6) chain motif extending along the c axis of the unit...

Numerous crystal structures are available for the dimeric amino acid cystine. In proteins it is formed by oxidation of the -SH thiol groups of two closely spaced cysteine residues, resulting in the formation of a familiar di-sulfide bridge. The title compound [systematic name: (R,R)-1,1'-dicarb-oxy-2,2'-(diselanedi-yl)diethanaminium dichloride], C6H14N2O4Se2 (2+)·2Cl(-), is the first example of...

The title compound, [Ru(C7F5O2)2(C10H14)(C21H24N2)]·2CH2Cl2, is formed as an orange crystalline powder by the reaction of RuCl2(p-cymene)(IMes) and AgOCOC6F5 in anhydrous tetra-hydro-furan (IMes = 1,3-dimesityl-2,3-di-hydro-1H-imidazol-2-yl-idene). The asymetric unit consists of two independent [Ru(C6F5COO)2(η(6)-p-cymene)(IMes)] com-plexes and four dichloro-methane solvent mol-ecules. In each ...

The asymmetric unit of the title hydrated salt, C(6)H(14)NO(2) (+)·F(-)·H(2)O, contains a discrete cation with a protonated amino group, a halide anion and one water mol-ecule. The crystal structure is composed of double layers parallel to (010) held together by N-H⋯O, N-H⋯F, O-H⋯F and C-H⋯F hydrogen bonds, forming a two-dimensional network, and stacked along the c axis, viz. hydro-philic layer...

Uninterruptible power supplies (UPS) have been used to sustain a continuous power supply to certain critical loads protecting them against unexpected power outages as well as over and under voltage conditions. It requires fast response, compensation and instant availability of electrical power. One of important components that considerably affect these characteristics is energy storage units li...

In the asymmetric unit of the title compound, 2C(7)H(9)ClN(+)·C(9)H(6)O(4) (2-)·2H(2)O, there are two crystallographically independent cations, one dianion and two water mol-ecules. The dihedral angle between the two carboxyl-ate groups of the dianion is 78.1 (2)°. In the crystal, the components are held together by N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds, forming a layer parallel to the bc plane...
