Crystal structure of dibenzoyl diselenide.
C14H10O2Se2 is monoclinic, P2(1)/c. The unit-cell dimensions at 293 K are a = 12.795(2), b = 12.126(2), c = 9.0179(13)A, beta = 107.074(6)degrees, V = 1337.5(3)A3, and Z = 4. The R value is 0.048 for 2319 observed reflections. The dihedral angle between the plane C4-C7(O2)-Se1 and C9-C8(O1)-Se2 is 85.6(2)degrees, keeping the Se atom unshared electron pairs in a more stable configuration with th...

متن کاملCrystal structure of 1,8-dibenzoyl-2,7-diphenoxynaphthalene
In the title compound, C36H24O4, the benzene rings of the benzoyl and phen-oxy groups make dihedral angles of 75.01 (4), 75.78 (4), 83.17 (5) and 80.84 (5)° with the naphthalene ring system. In the crystal, two types of C-H⋯π inter-actions between the benzene rings of the benzoyl groups and the naphthalene unit, and two kinds of π-π inter-actions between the benzene rings, with centroid-centroi...
متن کاملQTAIM study of Bonding and Structure of Pure Atomic Clusters,Part III : Nn Clusters (n= 4,6)
DFT and QTAIM computations have been performed on numbers of pure nitrogen cluster speciesi.e. Nn (n = 4, 6) for investigating the structure and bonding. This study is critical since thesemolecules have been nominated as the good synthetic targets of High Energy Materials (HEM).0nthe other hand the decomposition mechanism is closely depends on the bonding pattern. Thislatter concept was searche...
متن کاملFast k-NN search
Random projection trees have proven to be effective for approximate nearest neighbor searches in high dimensional spaces where conventional methods are not applicable due to excessive usage of memory and computational time. We show that building multiple trees on the same data can improve the performance even further, without significantly increasing the total computational cost of queries when...
