1,1'-Dimethoxy-3,3'-dimethyl-3,3'-(hexane-1,6-diyl)bis(triazen-2-ium-2-olate): a nitric oxide donor.

ABSTRACT: The title compound, C(10)H(24)N(6)O(4), is the most stable type of nitric oxide (NO) donor among the broad category of discrete N-diazeniumdiolates (NO adducts of nucleophilic small molecule amines). Sitting astride a crystallographic inversion center, the molecule contains a symmetric dimethylhexane-1,6-diamine structure bearing two planar O(2)-methylated N-diazeniumdiolate functional groups [N(O)=NOMe]. These two groups are parallel to each other and have the potential to release four molecules of NO. The methylated diazeniumdiolate substituent removes the negative charge from the typical N(O)=NO(-) group, thereby increasing the stability of the diazeniumdiolate structure. The crystal was nonmerohedrally twinned by a 180 degrees rotation about the real [101] axis. This is the first N-based bis-diazeniumdiolate compound with a flexible aliphatic main unit to have its structure analyzed and this work demonstrates the utility of stabilizing the N-diazeniumdiolate functional group by methylation.

1,1'-{(Hexane-1,6-di-yl)bis-[(aza-niumylyl-idene)methanylyl-idene]}bis-(naphthalen-2-olate).

Project description:The whole molecule of the title Schiff base compound, C28H28N2O2, is generated by inversion symmetry. It is formed from two units of ortho-hy-droxy-naphthaldehyde bridged with 1,6-di-amino-hexane. The N atoms are protonated and, thus, the structure is a bis-zwitterionic compound in the solid state. The zwitterion shows strong intra-molecular N-H⋯O hydrogen bonds between the iminium N and the naphthaleno-late O atoms.

Project description:The title compound, C(12)H(20)N(6)O(2), has a centre of symmetry. The mol-ecule consists of two triazole rings joined by an aliphatic -(CH(2))(6)- chain. The crystal structure is stabilized by inter-molecular N-H?O hydrogen bonds and by ?-? stacking inter-actions between the triazole rings of inversion-related mol-ecules [centroid-centroid distance = 3.277?(8)?Å].

Project description:In the title compound, C(11)H(18)N(4) (2+)·2PF(6) (-), the dihedral angle between the two planar imidozlium rings is 6.1?(2)°. Both [PF(6)](-) anions are disordered [occupancies 0.65?(2):0.35?(2) and 0.59?(5):0.41?(5)]. The crystal packing is stabilized by inter-molecular C-H?F hydrogen bonds which link two mol-ecules, forming centrosymmetric dimers.

3,3'-(2,2'-Bi-1H-imidazole-1,1'-diyl)dipropanol.

Project description:In the title compound, C(12)H(18)N(4)O(2), unlike other unconjugated disubstituted biimidazole derivatives reported so far, the two imidazole rings in a trans conformation exhibit a large planar rotation angle of 51.27?(4)°, and consist of half-mol-ecule asymmetric units related by a twofold rotation. The mol-ecules are linked into a three-dimensional framework with a parallel laminated construction via O-H?N and C-H?O inter-actions.

Project description:In the title mol-ecular salt, C(18)H(24)N(4) (2+)·2PF(6) (-), the complete dication is generated by a crystallographic inversion centre. The central benzene ring makes a dihedral angle of 77.19 (9)° with each of the imidazole rings. In the crystal, C-H⋯F inter-actions link the cations and anions into layers lying parallel to the bc plane. The hexa-fluoro-phosphate anion is disordered over two sets of sites in a 0.520 (11):0.480 (11) ratio.

2,2'-[1,1'-(Hexane-1,6-diyldioxy-dinitrilo)diethyl-idyne]diphenol.

Project description:The molecule of the title compound, C(22)H(28)N(2)O(2), lies across an inversion centre with one half-mol-ecule in the asymmetric unit. The mol-ecule adopts an E configuration with respect to the azomethine C=N bond and the imino group is coplanar with the aromatic ring. Within the mol-ecule, the planar units are parallel, but extend in opposite directions from the hexa-methyl-ene bridge. There are intra-molecular O-H?N hydrogen bonds between the hydroxyl groups and the oxime N atoms. There are also weak inter-molecular C-H?O bonds that link each mol-ecule to two others, forming chains along the a axis.

3,3'-Dimethyl-1,1'-[2,2'-bipyridine-5,5'-diylbis(methyl-ene)]diimidazol-3-ium bis-(hexa-fluoro-phosphate).

Project description:The title compound, C(20)H(22)N(6) (2+)·2PF(6) (-), was prepared by the reaction of 5,5'-bis-(bromo-meth-yl)-2,2'-bipyridine with 1-methyl-imidazole. The main mol-ecule lies on an inversion center located at the mid-point of the C-C bond joining the two pyridine rings. The asymmetric unit therefore contains one half-mol-ecule and one hexa-fluoro-phosphate anion. The dihedral angle between the pyridine and imidazole rings is 76.93 (7)°. In the crystal, weak inter-molecular C-H⋯F hydrogen bonds contribute to the stabilization of the packing.
