Naphthalene-1,8-di-amine-2-(pyrimidin-2-yl)-1H-perimidine (2/1).

ABSTRACT: In the title adduct, C15H10N4·2C10H10N2, the pyrimidine ring is nearly co-planar with the heteroatomic perimidine ring, as indicated dihedral angle between their mean planes of 3.21?(11)°. The di-aminona-phthalene mol-ecules are slightly twisted [dihedral angles = 4.2?(2) and 3.0?(2)°] because of the steric encumbrance of NH2 groups. The perimidine and di-aminona-phthalene mol-ecules are linked by N-H?N hydrogen bonds, forming an R (4) 4(12) graph-set motif across an inversion center. In the crystal, alternating layers of the perimidine and di-aminona-phthalene mol-ecules are formed along [100]. In the perimidine layer, mol-ecules are ?-? stacked along the c-axis direction with an inter-plane separation of approximately 3.4?Å.

(2,7-Dimethoxy-naphthalene-1,8-di-yl)bis-(4-fluoro-benzo-yl)dimethanone.

Project description:The title compound, C(26)H(18)F(2)O(4), is a naphthalene derivative in which the two aroyl groups at the 1- and 8-positions (peri positions) are anti to each other. There is an appreciable difference in the dihedral angles between the naphthalene ring system and the two benzene rings [66.88?(7)° and 88.09?(6)°]. In the crystal, weak C-H?O inter-actions involving one of the carbonyl groups and an aromatic C-H group ortho to the F atom seem to stabilize the packing of the mol-ecules.

N-(4,6-Dimethyl-pyrimidin-2-yl)-1H-benzimidazol-2-amine.

Project description:There are two independent mol-ecules in the asymmetric unit of the title compound, C(13)H(13)N(5). In each mol-ecule, an amino N atom is connected to a benzimidazole fused-ring system and a pyrimidine ring [these are aligned at 1.3 (1)° in one independent mol-ecule and at 5.4 (1)° in the other]. The amino N atom of the fused ring forms an intra-molecular N-H⋯O hydrogen bond to a pyrimidine N atom in each mol-ecule. The amino N atom connecting the two ring systems inter-acts with the other N atom of the pyrimidine ring of an adjacent mol-ecule, generating centrosymmetric hydrogen-bonded dimers.

Aqua-chlorido-(2-{[6-(di-methyl-amino)-pyrimidin-4-yl]sulfan-yl}pyrimidine-4,6-di-amine)-copper(II) chloride hydrate.

Project description:A copper(II) complex of the non-symmetric bidentate ligand 2-{[6-(di-methyl-amino)-pyrimidin-4-yl]sulfan-yl}pyrimidine-4,6-di-amine (L1) is reported. The single-crystal X-ray structure of aqua-[aqua/chlorido-(0.49/0.51)](2-{[6-(di-methyl-amino)-pyrimidin-4-yl]sulfan-yl}pyrimidine-4,6-di-amine)-copper(II) 0.49-chloride 1.51-hydrate, [CuCl1.51(C10H13N7S)(H2O)1.49]Cl0.49·1.51H2O or [(L1)Cl1.51(H2O)1.49Cu]0.49Cl·1.51H2O, exhibits distorted square-pyramidal geometry around the metal centre, with disorder in the axial position, occupied by chloride or water. The six-membered metal-chelate ring is in a boat conformation, and short inter-molecular S⋯S inter-actions are observed. In addition to its capacity for bidentate metal coordination, the ligand has the ability to engage in further supra-molecular inter-actions as both a hydrogen-bond donor and acceptor, and multiple inter-actions with lattice solvent water mol-ecules are present in the reported structure.
