9-(2-Chlorobenzylidene)anthracen-10(9H)-one
In the title compound, C21H13ClO, the central anthracene system is distorted towards a boat conformation and the outer rings are not coplanar with the central ring [dihedral angles = 7.79 (1) and 11.90 (1)°]. The crystal structure features inversion dimers with graph-set motif R 2 (2)(18) formed by C-H⋯O inter-actions.
متن کاملStructural, spectroscopic, and magnetic study of bis(9,10-dihydro-9-oxo-10-acridineacetate)bis(imidazole)bis(methanol) nickel(II).
The mixed ligand complex [Ni(CMA)2(im)2(MeOH)2] (where CMA = 9,10-dihydro-9-oxo-10-acridineacetate ion, im = imidazole) was prepared, and its crystal and molecular structure were determined. The nickel ions are hexa-coordinated by four oxygen atoms of the carboxylate and hydroxyl groups and by two imidazole nitrogen atoms, to form a distorted octahedral arrangement. The structure consists of a ...
متن کاملCosmic Rays I . The cosmic ray spectrum between 10 4 GeV and 3 10 9 GeV
Based on a conjecture about the diffusion tensor of relativistic particles perpendicular to the magnetic field at a shock, and considering particle drifts, I develop a theory to account for the Cosmic Ray spectrum between 10 GeV and 3 10 GeV. The essential assumption is that the free mean path perpendicular to the magnetic field is independent of energy and has the scale of the thickness of the...

This month’s editorials question the basis of some accepted beliefs, namely the benefit of minimising the time spent as an in-patient in hospital, and the reasons for favouring atypical antipsychotics in the treatment of schizophrenia. Capdevielle & Ritchie (pp. 164–165) debate the risks and benefits of shorter hospital stays and suggest that the shortest stays occur in countries where communit...

We discuss current approaches to the development of natural language dialogue systems, and claim that they do not sufficiently consider the unique qualities of man-machine interaction as distinct from general human discourse. We conclude that empirical studies of this unique communication situation is required for the development of user-friendly interactive systems. One way of achieving this i...
