چکیده
The asymmetric unit of the title compound, C(14)H(12)N(2)O(2), which was synthesized unexpectedly by refluxing an ethano-lic solution of isonicotinic hydrazide and 3-hydroxy-benzaldehyde, contains one half-mol-ecule with the center of the N-N bond lying on a crystallographic center of inversion. In the crystal structure, mol-ecules are linked by inter-molecular O-H⋯N hydrogen bonds into an infinite layer structure parallel to (110).

The mol-ecular structure of title compound, C(10)H(10)N(4)·H(2)O, has an inversion centre located on the mid-point of the N-N bond of the mol-ecule. A twofold rotation axis passes through the water O atom. In the crystal structure, a two-dimensional network is constructed through N-H⋯O and O-H⋯N hydrogen bonds.

The mol-ecule of the title compound, C(12)H(14)N(8)S(2), has an N-N gauche conformation. The triazine rings are nearly coplanar with respect to the imide bonds [C-C-C-N torsion angles = -15.3 (3) and -15.8 (3)°] and they are twisted by 77.88 (7)°. The overall conformation of the mol-ecule is stabilized by intra-molecular C-H⋯N hydrogen bonding. The mol-ecular packing is influenced by π-π inter-...

The Ni atom in the title linear supra-molecular polymer, [Ni(C(6)H(14)O(2)PS(2))(2)(C(12)H(10)N(4))](n), exists within a trans-N(2)S(4) octa-hedral donor set defined by two symmetrically coordinating dithio-phosphate ligands and pyridine N atoms derived from two bridging bis-(4-pyridylmethyl-ene)diazane ligands. The Ni atom lies on a centre of inversion and the bis-(4-pyridylmethyl-ene)diazane ...
متن کاملSynthesis of sterically encumbered 2,4-bis-m-terphenyl-1,3-dichloro-2,4-cyclo-dipnictadiazanes [m-TerNPnCl](2), (Pn = P, As).
The reaction of m-terphenyl amine (2,6-bis-(2,4,6-trimethylphenyl)aniline, m-Ter = m-terphenyl = 2,6-bis-(2,4,6-trimethylphenyl)) and ECl(3) (E = P, As) in the presence of different bases (Et(3)N, n-BuLi, LDA, DBU) and under different reaction conditions was studied. The reaction with excess Et(3)N yielded m-Ter-N(H)-AsCl(2) for E = As, while for E = P m-Ter-N(PCl(2))(2) was formed. m-Ter-N(H)-...
