5-(Adamantan-1-yl)-3-anilinomethyl-2,3-di-hydro-1,3,4-oxa-diazole-2-thione.

ABSTRACT: In the title compound, C19H23N3OS, the oxa-diazole and benzene rings are inclined at a dihedral angle of 50.30?(11)°, with the major twist between them occurring at the ring-methyl-ene N-C bond [N-N-C-N torsion angle = -101.2?(2)°]. In the crystal, helical supra-molecular chains along [010] are sustained by N-H?S hydrogen bonds. These are linked into layers lying parallel to (-101) by methyl-ene-phenyl C-H?? inter-actions.

Crystal structure of 3-[(4-benzyl-piperazin-1-yl)meth-yl]-5-(thio-phen-2-yl)-2,3-di-hydro-1,3,4-oxa-diazole-2-thione.

Project description:The title 1,3,4-oxa-diazole-2-thione derivative, C18H20N4OS2, crystallized with two independent mol-ecules (A and B) in the asymmetric unit. The 2-thienyl rings in both mol-ecules are rotationally disordered over two orientations by approximately 180° about the single C-C bond that connects it to the oxa-diazole thione ring; the ratios of site occupancies for the major and minor components were fixed in the structure refinement at 0.8:0.2 and 0.9:0.1 in mol-ecules A and B, respectively. The 1,3,4-oxa-diazole-2-thione ring forms dihedral angles of 7.71?(16), 10.0?(11) and 77.50?(12)° (mol-ecule A), and 6.5?(3), 6.0?(9) and 55.30?(12)° (mol-ecule B) with the major and minor parts of the disordered thio-phene ring and the mean plane of the adjacent piperazine ring, respectively, resulting in approximately V-shaped conformations for the mol-ecules. The piperazine ring in both mol-ecules adopts a chair conformation. The terminal benzene ring is inclined towards the mean plane of the piperazine ring with N-C-C-C torsion angles of -58.2?(3) and -66.2?(3)° in mol-ecules A and B, respectively. In the crystal, no inter-molecular hydrogen bonds are observed. The crystal packing features short S?S contacts [3.4792?(9)?Å] and ?-? inter-actions [3.661?(3), 3.664?(11) and 3.5727?(10)?Å], producing a three-dimensional network.

3-[(4-Phenyl-piperazin-1-yl)meth-yl]-5-(thio-phen-2-yl)-2,3-di-hydro-1,3,4-oxa-diazole-2-thione.

Project description:In the title compound, C17H18N4OS2, the 2-thienyl ring is disordered over two co-planar, opposite orientations in a 0.684?(2): 0.316 ratio. The 1,3,4-oxa-diazole ring is almost co-planar with the attached 2-thienyl ring [dihedral angles of 5.34?(19) and 4.8?(5)° for the major and minor components, respectively]. The relative disposition of the thione- and ring-S atoms is anti for the major orientation of the 2-thienyl residue. Overall, the shape of the mol-ecule approximates the letter V. In the crystal, a three-dimensional architecture is consolidated by a combination of weak C-H?S and C-H?? contacts.

Crystal structures and Hirshfeld surface analysis of 2-(adamantan-1-yl)-5-(4-fluoro-phen-yl)-1,3,4-oxa-diazole and 2-(adamantan-1-yl)-5-(4-chloro-phen-yl)-1,3,4-oxa-diazole.

Project description:The crystal structures of the title adamantane-oxa-diazole hybrid compounds, C18H19FN2O (I) and C18H19ClN2O (II), are built up from an adamantane unit and a halogenophenyl ring, [X = F (I), Cl (II)], in position 5 on the central 1,3,4-oxa-diazole unit. The mol-ecular structures are very similar, only the relative orientation of the halogenophenyl ring in comparison with the central five-membered ring differs slightly. In the crystals of both compounds, mol-ecules are linked by pairs of C-H?N hydrogen bonds, forming inversion dimers with R 2 2(12) ring motifs. In (I) the dimers are connected by C-H?F inter-actions, forming slabs lying parallel to the bc plane. In (II), the dimers are linked by C-H?? and offset ?-? inter-actions [inter-planar distance = 3.4039?(9)?Å], forming layers parallel to (10).

Project description:In title compound, [PtCl2(C15H21N3O2)2], the Pt(II) cation, located on an inversion center, is coordinated by two Cl(-) anions and two 3-(4-meth-oxy-phen-yl)-2-methyl-5-(piperidin-1-yl)-2,3-di-hydro-1,2,4-oxa-diazole ligands in a distorted Cl2N2 square-planar geometry. The di-hydro-oxa-diazole and piperidine rings display envelope (with the non-coordinating N atom as the flap atom) and chair conformations, respectively. In the crystal, weak C-H?Cl hydrogen bonds link the mol-ecules into supra-molecular chains running along the b axis. The piperidine ring is disordered over two positions with the occupancy ratio of 0.528?(4):0.472?(4).

Project description:The title compound, C18H20N4O2S2, is a new 1,3,4-oxa-diazole and a key pharmacophore of several biologically active agents.

The thio-phene ring mean plane lies almost in the plane of the oxa-diazole ring, with a dihedral angle of 4.35 (9)°. The 2-meth-oxy-phenyl ring is almost normal to the oxa-diazole ring, with a dihedral angle of 84.17 (10)°. In the crystal, mol-ecules are linked by weak C-H⋯S hydrogen bonds and C-H⋯π inter-actions, forming layers parallel to the bc plane. The layers are linked via weak C-H⋯O hydrogen bonds and slipped parallel π-π inter-actions [inter-centroid distance = 3.6729 (10) Å], forming a three-dimensional structure. The thio-phene ring has an approximate 180° rotational disorder about the bridging C-C bond.
