[?-Bis(5,7-dimethyl-1,8-naphthyridin-2-yl)diazene]bis-[difluoridoboron(III)].

ABSTRACT: In the title compound, C(20)H(18)B(2)F(4)N(6), the bis-(5,7-dimethyl-1,8-naphthyridin-2-yl)diazene molecule is bis-ected by a symmetry centre midway between the central N atoms of the diazene group. Each of the symmetry-related halves of the molecule binds to a B atom through an N,N'-bite. Two terminal F ions complete the distorted BN(2)F(2) tetra-hedral geometry around each B atom. The BF(2) plane is almost perpendicular to the boron-naphthyridine ring plane, with a dihedral angle of 87.8?(2)°. The main inter-actions in the crystal structure are some C-H?F hydrogen bonds and ?-? contacts between 1,8-naphthyridine rings [centroid-centroid distance = 4.005?(1)?Å].

2,6-Diamino-pyridinium tetra-phenyl-borate-1,2-bis-(5,7-dimethyl-1,8-naphthyridin-2-yl)diazene (1/1).

Project description:In the title compound, C(5)H(8)N(3) (+)·C(24)H(20)B(-)·C(20)H(18)N(6), the 1,2-bis-(5,7-dimethyl-1,8-naphthyridin-2-yl)diazene mol-ecule is essentially planar (r.m.s. deviation = 0.0045?Å) and aligned in nearly coplanar manner with the 2,6-diamino-pyridinium ion, making a dihedral angle of 5.19?(5)°. The diamino-pyridine mol-ecule is protonated on the central pyridine N atom and the B atom bears the counter-charge. The amine groups of the diamino pyridinium cation form intra-molecular N-H?N hydrogen bonds, resulting in linear and bent inter-actions with the naphthyridine ring system.

Crystal structures of the dioxane hemisolvates of <i>N</i>-(7-bromo-methyl-1,8-naphthyridin-2-yl)acetamide and bis-[<i>N</i>-(7-di-bromo-methyl-1,8-naphthyridin-2-yl)acetamide].

Project description:The syntheses and crystal structures of N-(7-bromo-methyl-1,8-naphthyridin-2-yl)acetamide dioxane hemisolvate, C11H10BrN3O·0.5C4H8O2, (I), and bis-[N-(7-di-bromo-methyl-1,8-naphthyridin-2-yl)acetamide] dioxane hemisolvate, 2C11H9Br2N3O·0.5C4H8O2, (II), are described. The mol-ecules adopt a conformation with the N-H hydrogen pointing towards the lone electron pair of the adjacent naphthyridine N atom. The crystals of (I) are stabilized by a three-dimensional supra-molecular network comprising N-H⋯N, C-H⋯N and C-H⋯O hydrogen bonds, as well as C-Br⋯π halogen bonds. The crystals of compound (II) are stabilized by a three-dimensional supra-molecular network comprising N-H⋯N, C-H⋯N and C-H⋯O hydrogen bonds, as well as C-H⋯π contacts and C-Br⋯π halogen bonds. The structure of the substituent attached in the 7-position of the naphthyridine skeleton has a fundamental influence on the pattern of inter-molecular noncovalent bonding. While the Br atom of (I) participates in weak C-Br⋯Oguest and C-Br⋯π contacts, the Br atoms of compound (II) are involved in host-host inter-actions via C-Br⋯O=C, C-Br⋯N and C-Br⋯π bonding.

N-(Pyrazin-2-yl)-1,8-naphthyridin-2-amine.

Project description:There are two independent mol-ecules in the asymmetric unit of the title compound, C12H9N5, in which the C-N(amine)-C angles differ slightly [129.63?(11) and 132.02?(11)°]. In each independent mol-ecule, an intra-molecular C-H?N hydrogen bond stabilizes the mol-ecular structure, forming an S(6) ring motif. The independent mol-ecules are linked via an N-H?N hydrogen bond. Further N-H?N and C-H?N hydrogen bonds connect the mol-ecules into chains along c axis. Pairs of C-H?? inter-actions between the chains lead to sheets parallel to the b axis. These are linked by ?-? inter-actions between the naphthyridine and pyrazine rings [centroid-centroid separations of 3.553?(8)?Å] into a three-dimensional supra-molecular network.

Project description:In the centrosymmetric dimeric title complex, [Fe(2)(C(14)H(10)N(2)O(4))(2)Cl(2)(C(2)H(6)OS)(2)]·2C(2)H(6)OS, two {Fe(L)Cl(DMSO)} units (L is the tridentate ligand 4-nitro-2-{[2-(oxidometh-yl)phen-yl]imino-meth-yl}phenolate; DMSO is dimethyl sulfoxide) are bridged by two O atoms, with an Fe?Fe separation of 3.1838?(8)?Å. The coordination polyhedron of the Fe(III) atoms can be described as distorted octa-hedral, with four Fe-O, one Fe-N and one Fe-Cl coordination bonds. The L ligand is not planar, the dihedral angle between the 2-(oxidometh-yl)phen-yl]imino and 4-nitro-2-(imino-meth-yl)phenolate planes being 48.54?(9)°. The solvent DMSO molecule is disordered over two orientations with equal occupancy.

Bis(cyanato-κN)bis-(5,7-dimethyl-1,2,4-triazolo[1,5-a]pyrimidine-κN)zinc.

Project description:In the title complex, [Zn(NCO)(2)(C(7)H(8)N(4))(2)], the Zn(II) ion exhibits a distorted tetra-hedral coordination geometry. The coordination environment is formed by two 5,7-dimethyl-1,2,4-triazolo[1,5-a]pyrimidine (dmtp) ligands, coordinated through the N atom in position 3, and two cyanate anions inter-acting by their N atoms. Supra-molecular dimers are generated by stacking inter-actions between the pyrimidine rings of two ligands related by an inversion center [centroid-centroid distance = 3.5444 (18) Å].

Bis(7-amino-2,4-dimethyl-1,8-naphthyridine)dinitratocadmium(II).

Project description:In the title compound, [Cd(NO(3))(2)(C(10)H(11)N(3))(2)], two naph-thyridine ring systems are coordinated to the Cd ion through the two N atoms in a bidentate chelating mode, whereas the remaining coordination sites are occupied by two O atoms from two different nitrate groups to complete the octahedral geometry. Inter-moleular N-H?O hydrogen bonds link the mol-ecules to form a one-dimensionnal sheet parallel to the ac plane. Weak slipped ?-? stacking involving the naphthyridine ring systems stabilizes the structure.
