The crystal and molecular structure of the potassium salt of 2,2,5,5-tetramethyl-3-carboxypyrroline-1-oxyl.
The crystal structure of the potassium salt of 2,2,5,5-tetramethyl-3-carboxypyrroline-1-oxyl (I), which is a free radical of the nitroxide type, has been determined by three-dimensional X-ray methods. The unit cell contains two crystallographically different types of molecule, one of which lies with its five-membered ring entirely in a mirror plane and is therefore perfectly flat. Molecules of ...
متن کاملCrystal structure of 3-bromopyridine N-oxide
In the title compound, C5H4BrNO, there are two mol-ecules in the asymmetric unit that are related by a pseudo-inversion center. The two independent mol-ecules are approximately planar, with an observed (ring-ring) angle of 5.49 (13)°. The crystal structure exhibits a herringbone pattern with the zigzag running along the b-axis direction. The least-squares plane containing the rings of both asym...
متن کاملCrystal structure of tert-butyldiphenylphosphine oxide
In the structure of the title triorganophosphine oxide, C16H19OP, the P-O bond is 1.490 (1) Å. The P atom has a distorted tetrahedral geometry. The O atom inter-acts with both phenyl groups of a neighboring mol-ecule [C⋯O = 2.930 (3) and 2.928 (4) Å]. The C-O interaction directs an extended supramolecular arrangement along the a-axis.

before collision. No drop is seen at 5.4 volts which would correspond to the loss of 10.4 volts which is normally assumed to take place at ionization. From curves of such nature for different velocities of impact, it has been possible to determine more surely than heretofore the energy losses at electron impact. The outstanding results of the investigation are: 1. The discovery by Mohler, Foote...
متن کاملThe crystal structure of p-type transparent conductive oxide CuBO2
We employed ab initio global structural prediction algorithms to obtain the ground-state structure of CuBO2 This is a very promising p-type transparent conductive oxide that was synthesized recently, and thought to belong to the delafossite family. We proved that the true ground state is certainly not the delafossite structure, and that the most promising candidate is a low symmetry monoclinic ...
