Bis{?-2,5-bis-[4-(2-pyridylmethyl-amino)phen-yl]-1,3,4-oxadiazole}bis-[dichlorido-mercury(II)].

ABSTRACT: In the title centrosymmetric compound, [Hg(2)Cl(4)(C(26)H(22)N(6)O)(2)], each Hg(II) center adopts a distorted HgN(3)Cl(2) trigonal bipyramidal coordination geometry, formed by two pyridine N atoms, one imine N atom and two chloride anions. Within the organic ligand, the oxadiazole ring is nearly coplanar with the two benzene rings [dihedral angles = 5.9?(4) and 6.5?(4)°] and nearly perpendicular to the two pyridine rings with the same dihedral angle of 77.4?(4)°. The two organic ligands bridge two Hg(II) ions to form the macrocyclic complex. Inter-molecular N-H?Cl and N-H?N hydrogen bonding helps to stabilize the crystal structure.

Project description:In the title hydrated salt, C36H66N8O(6+)·6ClO4(-)·1.5H2O, the asymmetric unit consists of a hexa-protonated [H6L](6+) cation, five perchlorate anions in general positions, two on twofold rotation axes (one of which is disordered), and two water mol-ecules of crystallization in general positions, one of them disordered around a twofold crystallographic axis. In the [H6L](6+) cation, two strong intra-molecular N-H?N hydrogen bonds occur, involving the N atoms of the oxadiazole ring as acceptors and the closest NH(+) groups of each dipropyl-enetriamine unit. In the crystal, the [H6L](6+) cations form channels along the a-axis direction, in which the perchlorate counter-ions and the water mol-ecules are lodged. The crystal packing features a network of N-H?O and O-H?O hydrogen bonds involving the NH(+) groups of the [H6L](6+) cation, the perchlorate anions and the water mol-ecules.

catena-Poly[[dianilinedichloridocopper(II)]-?(2)-2,5-bis-(4-pyrid-yl)-1,3,4-oxadiazole].

Project description:In the title compound, [CuCl(2)(C(6)H(7)N)(2)(C(12)H(8)N(4)O)](n), the Cu atom, located on an inversion center, is coordinated by four N atoms from two aniline ligands and two 2,5-bis-(4-pyrid-yl)-1,3,4-oxadiazole ligands. Two Cl atoms lying above and below the plane formed by these four N atoms inter-act weakly with the Cu atom [Cu-Cl = 2.7870?(7)?Å]. The trans 2,5-bis-(4-pyrid-yl)-1,3,4-oxadiazole ligands act as bridging ligands, linking adjacent Cu atoms and forming a one-dimensional coordination polymer. Two anilines coordinate with each Cu atom as terminal groups. The structure contains two classical N-H?Cl and two non-classical C-H?Cl hydrogen bonds.

5,5'-Bis(naphthalen-2-yl)-2,2'-bi(1,3,4-oxadiazole).

Project description:The title mol-ecule, C(24)H(14)N(4)O(2), lies on an inversion centre and the asymmetric unit containg one half-mol-ecule. The naphthalene ring systems are twisted slightly with respect to the oxadiazole rings, making a dihedral angle of 1.36?(6)°. These mol-ecules are ?-stacked along the crystallographic a axis, with an inter-planar distance of 3.337?(1)?Å. Adjacent mol-ecules are slipped from the 'ideal' cofacial ?-stack in both the long and short mol-ecular axis (the long mol-ecular axis is defined as the line through the naphthalene C atom in the 6-position and the mol-ecular center, the short mol-ecular axis is in the mol-ecular plane perpendicular to it). The slip distance along the long mol-ecular axis (S(1)) is 7.064?(1)?Å, nearly a two-ring-length displacement. The side slip (S(2), along the short mol-ecular axis) is 1.159?(8)?Å.
