(2,2′-Bipyridine)bis(triphenylphosphine)copper(I) nitrate chloroform solvate hemihydrate

(2,2′-Bipyridine)bis­(triphenyl­phosphine)copper(I) nitrate chloro­form solvate hemihydrate

In the title compound, [Cu(C(10)H(8)N(2))(C(18)H(15)P)(2)]NO(2)·CHCl(3)·0.5H(2)O, the Cu atom is tetra-hedrally coordinated by a bidentate 2,2'-bipyridine ligand and two PPh(3) ligands. The Cu-N and Cu-P distances are similar to those observed in similar compounds. The range of coordination angles shows a moderate distortion from ideal tetra-hedral geometry. The bipyridine ligand is twisted [14...

N-[2-(2,2-Di­methyl­propanamido)­pyrimidin-4-yl]-2,2-di­methyl­propanamide n-hexane 0.25-solvate hemihydrate

The asymmetric unit of the title compound, C14H22N4O2·0.25C6H14·0.5H2O, contains two independent mol-ecules of 2,4-bis-(pivaloyl-amino)-pyrimidine (M) with similar conformations, one water mol-ecule and one-half n-hexane solvent mol-ecule situated on an inversion center. In one independent M mol-ecule, one of the two tert-butyl groups is rotationally disordered between two orientations in a 3:2...

Crystal structure of (E)-4-{4-[eth­yl(2-hydroxy­eth­yl)amino]­styr­yl}-1-methyl­pyridinium nitrate hemihydrate

The asymmetric unit of the title compound, C18H23N2O(+)·NO3 (-)·0.5H2O, contains two independent 4-{4-[eth-yl(2-hy-droxy-eth-yl)amino]-styr-yl}-1-methyl-pyridin-1-ium cations, two nitrate anions and one lattice water mol-ecule. In the cations, the pyridine ring is twisted with respect by 7.98 (12) and 18.42 (10)° to the benzene ring. In the crystal, the cations, the anions and the lattice water...

Chloroform

It was perhaps fitting that Lieut.-Colonel Edward Lawrie, should signalise the year of his retirement from the post of R,esidenc\r Surgeon at Hyderabad by the publication of a volume on Chloroform, a subject with which he has been identified for many years past, and in defence of his views on which, and those of his master Syme, he has fought non sine gloria for many }7ears. The introduction to...
