Crystal structure of (S)-5,7-diphenyl-4,7-dihydrotetrazolo[1,5-a]pyrimidine
The title compound, C16H13N5, was synthesized by coupling amino-tetra-zole with chalcone in the presence of an amine organocatalyst derived from chincona alkaloid. There are two mol-ecules, A and B, in the asymmetric unit. In mol-ecule A, the dihedral angles between the partly hydrogenated pyrimidine ring system (r.m.s. deviation = 0.056 Å) and the sp (2)- and sp (3)-bonded phenyl groups are 33...

In the title mol-ecule, C16H13N5, the plane of the tetra-zole ring forms dihedral angles of 16.37 (7) and 76.59 (7)° with the two phenyl rings. The dihedral angle between the phenyl rings is 68.05 (6)°. The pyrimidine ring is in a flattened boat conformation. In the crystal, mol-ecules are linked by pairs of N-H⋯N hydrogen bonds, forming inversion dimers.

component for functional dyes because it contains two electronwithdrawing and one electron-donating groups. Studies to understand how substituents to the 1H-pyrrole-2,5-dione skeleton influence its structure and properties are of particular interest from the viewpoint of the development of novel functional dyes. We determined the structure of 1,3,4triphenyl-pyrrole-2,5-dione (Fig. 1(I))1 and de...
متن کاملDiphenyl [(S)-1-phenylpropanamido]phosphate
The title compound, C(21)H(22)NO(3)P, was synthesized from the reaction of (C(6)H(5)O)(2)P(O)(Cl) and S-1-phenyl-propyl-amine (1:2 mole ratio) at 273 K, followed by removal of the S-1-phenyl-propyl-amine hydro-chloride by-product by dissolving in H(2)O. The P atom is located in a distorted tetra-hedral environment. The bond angles at the P atom vary from 99.51 (12) to 116.68 (12)°. The sp(2) ch...

The structures and some properties of water molecules, small water clusters (dimer of water molecules, three and four water molecules in configurations such as those found in cubic ice and six membered rings of water molecules) have been studied using bothgradientcorrected density functional theory with a plane wave basis set and Hartree-Fock using an ab initio 6-31++G basis set with and withou...
