ABSTRACT: In the title spiro-phosphazene derivative, C33H46N9OP3, the phosphazene and six-membered N/O rings are in flattened chair and twisted-boat conformations, respectively. The naphthalene ring system and the pyridine ring are oriented at a dihedral angle of 41.82?(4)°. In the crystal, weak C-H?O hydrogen bonds link the mol-ecules related by translation along the a axis into chains. C-H?? inter-actions aggregate these chains into layers parallel to the ab plane.

Project description:The title compound, C26H22N5O4P3·C3H6O, has been achieved in a two-step synthesis that does not require chromatography. This mol-ecule contains a seven-membered spiro-cyclic ring at two P-atom positions and a five-membered ring containing new P-N bonds at the other P-atom position. Endocyclic torsion angles about the central biphenyl C-C bonds are -41.5?(3) and -44.4?(3)°, and P-N bonds of the central P3N3 ring are within the range 1.5665?(17)-1.6171?(17)?Å, while the P-O distances are in the range 1.5940?(14)-1.6041?(14)?Å. One N-H group makes an inter-molecular N-H?N hydrogen bond, forming centrosymmetric dimers, while the other N-H group makes an N-H?O hydrogen bond to the acetone solvent mol-ecule. The crystal was a two-component non-merohedral twin with ratio 0.811/0.189.

3'-(4-Chloro-benzo-yl)-4'-(4-chloro-phen-yl)-1'-methyl-spiro-[indoline-3,2'-pyrrolidin]-2-one.

Project description:In the title compound, C(25)H(20)Cl(2)N(2)O(2), the pyrrolidine ring adopts an envelope conformation and the best plane through the five ring atoms makes a dihedral angle of 87.03?(8)° with the indoline ring. Mol-ecules are connected by pairs of N-H?O hydrogen bonds into centrosymmetric dimers with an R(2) (2)(8) graph-set ring motif. C-H?O hydrogen bonds stabilize the crystal structure.

2-(4-Meth-oxy-phen-yl)-4H-1,3,2-benzoxathia-phosphinine 2-sulfide.

Project description:The asymmetric unit of the title compound, C(14)H(13)O(2)PS(2), contains two crystallographically independent mol-ecules, which differ in the conformation of the 1,3,2-benzoxathia-phosphinine moieties (screw boat in the first mol-ecule and envelope in the second mol-ecule). In the crystal, neither classical nor non-classical hydrogen bonds are found. Weak inter-actions (about 2.9-3.0 Å) between the lone pair of the terminal S atoms with H atoms occur. This compound was further characterized by (1)H NMR and IR spectroscopy.

2-(4-Chloro-phen-yl)naphtho-[1,8-de][1,3,2]diaza-borinane.

Project description:The title compound, C(16)H(12)BClN(2), is one in a series of diaza-borinanes, derived from 1,8-diaminona-phthalene, featuring substitution at the 1, 2 and 3 positions in the nitro-gen-boron heterocycle. The structure deviates from planarity, the torsion angle subtended by the p-chloro-phenyl ring relative to the nitro-gen-boron heterocycle being -44-.3(3)°. The mol-ecules form infinite chains with strong inter-actions between the vacant pz orbital of the B atom and the ?-system of an adjacent mol-ecule. The distance between the B atom and the 10-atom centroid of an adjacent naphthalene ring is 3.381?(4)?Å. One N-H H atom is weakly hydrogen bonded to the Cl atom of an adjacent mol-ecule. This combination of inter-molecular inter-actions leads to the formation of an infinite two-dimensional network perpendic-ular to the c axis.

The non-planar cyclo-triphosphazene ring accommodates two Cd ions, and only four out of six exocylcic pyrazolyl ligands are bound to the Cd metal atoms. Each of these two symmetry-related Cd atoms is coordinated by two bidentate nitrato ligands, two exocylic pyrazolyl N atoms, and one cyclo-triphosphazene N atom.

2-Phenyl-naphtho-[1,8-de][1,3,2]diaza-borinane.

Project description:The title compound, C(16)H(13)BN(2), is one compound in a series of diaza-borinanes featuring substitution at the 1, 2 and 3 positions in the nitro-gen-boron heterocycle.

In the crystal, mol-ecules are linked by ?-? inter-actions into columns, with a distance of 3.92?(3)?Å between the naphthalene ring centroids. Adjacent ?-stacked columns, co-linear with the b-axis, are linked by C-H?? inter-actions.
