4,4′-[1,1′-Binaphthalene-2,2′-diyldi(oxymethylene)]benzonitrile

Abstract: In the title compound, C36H24N2O2, the two naphthyl systems are approximately perpendicular to each other and the two 4-cyano­benz­yloxy rings are almost parallel to each other. There are strong π–π inter­actions [3.835 (3) A] between neighbouring mol­ecules. The face-to-face π–π inter­actions between the benzene rings of neighbouring mol­ecules stabilize the crystal structure to form a one-dimensional chain structure along the a axis.

catena-Poly[[chlorido[(1S,2S)-cyclo­hexane-1,2-diamine-κ2N,N′]copper(II)]-μ3-chlorido]

Abstract: In the repeat unit of the title compound, [CuCl2(C6H14N2)], there are two chiral C atoms with an S configuration. In the crystal packing, one Cl atom plays an important role, acting as a bridge linking neighboring units, forming a polymeric one-dimensional ladder-like structure. The Cu atom has an approximately square-planar primary coordination geometry, with the bridging Cl atoms forming much longer bonds in the axial positions.

Triaqua(5-methyl-1H-tetrazolato-κN1)zinc(II) perchlorate

Abstract: The title compound, [Zn(C2H3N4)(H2O)3]ClO4, consists of one ZnII complex cation and one uncoordinated perchlorate anion. Both anion and cation lie on mirror planes. The ZnII ion displays a distorted tetra­hedral geometry and is coordinated by three O atoms and one N atom. Classical O—H⋯O and O—H⋯N hydrogen-bond inter­actions connect cations and anions to form a one-dimensional chain along [010].

4-Cyano-anilinium perchlorate.

Abstract: The title compound, C7H7N2+·ClO4−, comprises discrete ions which are inter­connected by N—H⋯O hydrogen bonds, leading to a neutral one-dimensional network along the [100] direction.

3,3′-{1,1′-Methyl­enebis[naphthalene-2,1-diylbis(oxymethyl­ene)]}dibenzonitrile

Abstract: The title compound, C37H26N2O2, was synthesized from 1,1′-methyl­enedinaphthalen-2-ol and 3-(bromo­methyl)­benzo­nitrile. The two naphthyl systems are almost perpendicular to each other [dihedral angle 83.3 (9)°] and the two cyano­benz­yloxy rings approximately parallel to each other [dihedral angle 15.5 (2)°].

4-(6-Quinolyl­oxymeth­yl)benzonitrile

Abstract: The title compound, C17H12N2O, was synthesized by an ether synthesis from quinolin-6-ol and 4-(bromo­meth­yl)benzonitrile. The phenyl ring of the benzonitrile group makes a dihedral angle of 47.52 (6)° with the plane of the quinoline fragment. The crystal structure is stabilized by inter­molecular C—H⋯π inter­actions between a benzene H atom of the benzonitrile group and the benzene ring of the quinoline fragment. In addition, the crystal structure also exhibits a weak inter­molecular C—H⋯N hydrogen bond.

4,4'-(Oxydimethyl-ene)dibenzonitrile.

Abstract: The title compound, C16H12N2O, was accidentally synthesized by the reaction of 4-(bromo­meth­yl)benzonitrile and penta­erythritol. The dihedral angle between the benzene rings is 57.39 (9)°. In the crystal structure, mol­ecules are linked by inter­molecular C—H⋯N hydrogen-bonding inter­actions to form chains running parallel to the b axis.
