3-{5-Bromo-2-[(tri-phenyl-phosphanyl-idene)amino]-phen-yl}-4,5-di-hydro-1,2,3-oxa-diazol-3-ylium-5-olate.

ABSTRACT: In general, sydnone compounds are synthesized with an aromatic substituent at the N-3 position and this feature adds to the stability of the mesoionic five-membered heterocyclic ring. In the title compound, C26H19BrN3O2P, the aromatic substitutent is tri-phenyl-phosphine 4-bromo-phenyl-imide. The dihedral angle between the planes of the sydnone and the attached phenyl ring is 45.98?(7)°. In the crystal, the mol-ecules packed as pairs in which the sydnone rings lie in parallel planes separated by 0.849?Å and sandwiched between two parallel phenyl rings. The mol-ecules inter-act through cyclic C-H?O=C hydrogen bonds.

2,9-Bis(5-sulfanylidene-4,5-di-hydro-1,3,4-oxa-diazol-2-yl)-1,10-phenanthroline dimethyl sulfoxide disolvate.

Project description:In the title compound, C16H8N6O2S2·2C2H6OS, the phenanthroline mol-ecule resides on a twofold axis, and the asymmetric unit also contains a slightly disordered [occupancy ratio for S atom of 0.95 (3):0.047 (3)] mol-ecule of dimethyl sulfoxide. The O atoms of the solvent mol-ecule accept hydrogen bonds from the N-H groups of the five-membered 2,3-di-hydro-1,3,4-oxa-diazole-2-thione ring. This ring is nearly coplanar with the phenanthroline ring, with a dihedral angle between their least-squares planes of 8.86 (6)°. In the crystal, the mol-ecules are linked by C-H⋯O inter-actions.

3-(4-Methyl-phen-yl)-4-[(thio-semi-carba-zono)meth-yl]-1,2,3-oxa-diazol-3-ium-5-olate 1,4-dioxane hemisolvate.

Project description:The asymmetric unit of the title compound, C11H11N5O2S·0.5C4H8O2, contains one 3-(p-tol-yl)sydnone 4-thio-semi-carba-zone mol-ecule and a half mol-ecule of 1,4-dioxane, which lies abount an inversion centre. The sydnone ring is almost planar, with a maximum deviation of 0.002?(1)?Å, and forms a dihedral angle of 46.31?(5)° with the benzene ring. In the crystal, the two components are linked into a tape along [01-1] by N-H?O and N-H?S hydrogen bonds. The crystal structure is further stabilized by C-H?O and C-H?? inter-actions, forming a three-dimensional network.

N-[4-Acetyl-5-(4-fluoro-phen-yl)-4,5-di-hydro-1,3,4-thia-diazol-2-yl]acetamide.

Project description:The title mol-ecule, C12H12FN3O2S, shows a short intra-molecular S⋯O contact of 2.682 (18) Å. The dihedral angle between the thia-diazole ring and the benzene ring is 86.82 (11)°. In the crystal, N-H⋯O and C-H⋯O hydrogen bonds generate an R 2 (1)(6) graph-set motif between adjacent mol-ecules. Pairs of futher C-H⋯O hydrogen bonds form inversion dimers with R 2 (2)(8) ring motifs. These combine to generate a three-dimensional network and stack the mol-ecules along the b axis.

Project description:In the title compound, C18H21F3N4O4, the piperazine ring adopts a chair conformation and the dihedral angle between the oxa-diazole and benzene rings is 6.45?(14)°. The C atoms and their attached H atoms in the piperazine ring are disordered, with site-occupation factors of 0.576?(12) and 0.424?(12). In the crystal, mol-ecules are linked through weak C-H?O inter-actions, generating an R 2 (2)(12) motif. Further, secondary C-H?O inter-molecular inter-actions link the mol-ecules into C(6) chains along [100].

Anomalous halogen bonds in the crystal structures of 1,2,3-tri-bromo-5-nitro-benzene and 1,3-di-bromo-2-iodo-5-nitro-benzene.

Project description:The title trihalogenated nitro-benzene derivatives, C6H2Br3NO2 and C6H2Br2INO2, crystallize in triclinic and monoclinic cells, respectively, with two mol-ecules per asymmetric unit in each case. The asymmetric unit of the tri-bromo compound features a polarized Br(δ+)⋯Br(δ-) inter-molecular halogen bond. After substitution of the Br atom in the para position with respect to the nitro group, the network of X⋯X halogen contacts is reorganized. Two inter-molecular polarized halogen bonds are then observed, which present the uncommon polarization Br(δ+)⋯I(δ-): the more electronegative site (Br) behaves as a donor and the less electronegative site (I) as an acceptor for the charge transfer.

There is a short O?N contact [2.83?(3)?Å] in the minor component. In the major component, the mol-ecular structure is stabilized by an intra-molecular C-H?O hydrogen bond, which forms an S(6) ring motif.
