Theoretical Investigation on Structural Properties of Ethylene Clusters (c 2 H 4 ) N (n ≤ 25)
Geometries of ethylene clusters (C 2 H 4) n in the range of n ≤ 25 are optimized with the intermolecular potential based on the ab initio calculations of the dimer. The heuristic method combined with geometrical perturbations is used for geometry optimization. Ethylene clusters do not take the icosahedral motif characteristic of some van der Waals molecular clusters. The structural evolution of...
متن کاملN′′-(4-Methoxyphenyl)-N,N,N′-trimethyl-N′-phenylguanidine
In the title compound, C17H21N3O, the C-N bond lengths in the guanidine unit are 1.2889 (19), 1.3682 (19) and 1.408 (2) Å, indicating double- and single-bond character. The N-C-N angles are 115.10 (13), 119.29 (15) and 125.61 (14)°, showing a deviation of the CN3 plane from an ideal trigonal-planar geometry. In the crystal, non-classical C-H⋯O hydrogen bonds between methyl H atoms and meth-oxy ...
متن کاملN,N′-Dibenzyl-N′′-(4-bromobenzoyl)-N,N′-dimethylphosphoric triamide
In the title compound, C(23)H(25)BrN(3)O(2)P, the P atom has a distorted tetra-hedral coordination. In the crystal structure, the mol-ecules form centrosymmetric dimers via pairs of essentially linear N-H⋯O hydrogen bonds.

The C-N bond lengths in the guanidine unit of the title compound, C16H18N4O2, are 1.298 (2), 1.353 (2) and 1.401 (3) Å, indicating double- and single-bond character. The N-C-N angles are 115.81 (16), 118.90 (18) and 125.16 (18)°, showing a deviation of the CN3 plane from an ideal trigonal-planar geometry. In the crystal, C-H⋯O hydrogen bonds are observed between the methyl- and aromatic-H atoms...
متن کامل(N 4-n-Butylpyridine-4-carbothioamide-κN 4)chloridobis(dimethylglyoximato-κ2 N,N′)cobalt(III) hemihydrate
The title compound, trans-[Co(C(4)H(7)N(2)O(2))(2)Cl(C(10)H(14)N(2)S)]·0.5H(2)O, contains two independent mol-ecules in the asymmetric unit in which the Co(III) ions are coordinated in slightly distorted octa-hedral coordination environments. The bis-chelating glyoximate ligands, which occupy equatorial sites, are linked by interligand O-H⋯O hydrogen bonds. The dihedral angles between the mean ...
