Cd Nuclear Quadrupole Interaction in CdCl 2 and its Monohydrate
The nuclear quadrupole interaction (NQI) in layered transition metal dichalcogenides usually decreases linearly with increasing temperature [1]. This behaviour was attributed to anisotropic lattice vibrations and is the two-dimensional analog of the Tpower law in three dimensions [2], In order to investigate the origin of this linear power law further we choose another layered compound, namely ...
متن کامل2-(4-Bromophenyl)quinoxaline
In the title compound, C(14)H(9)BrN(2), the benzene and quinoxaline rings are almost coplanar [r.m.s. deviation = 0.0285 (3) Å and dihedral angle = 2.1 (2)°].
متن کاملQuinoxaline-2-carbonitrile
In the title compound, C(9)H(5)N(3), the quinoxaline ring is essentially planar, with a maximum deviation of 0.012 (1) Å. Short inter-molecular distances between the centroids of the 2,3-dihydro-pyrazine and benzene rings [3.6490 (5) Å] indicate the existence of π⋯π inter-actions. In the crystal packing, the mol-ecules are linked via two pairs of inter-molecular C-H⋯N inter-actions, forming R(2...
متن کامل2-(4-Chloroanilino)quinoxaline
There are two mol-ecules in the asymmetric unit of the title compound, C(14)H(10)ClN(3), with dihedral angles of 5.11 (10) and 13.61 (10)° between the aromatic ring systems. In the crystal structure, mol-ecules are linked by N-H⋯N hydrogen bonds, resulting in chains propagating in [010].
متن کاملQuinoxaline: Z′ = 1 form
A new Z' = 1 crystal structure of quinoxaline (or 1,4-diaza-naphthalene), C(8)H(6)N(2), with one-fifth the volume of the earlier known Z' = 5 structure was obtained by means of an in situ cryocrystallization technique.
