2,8-Dimethyl-10-p-tolyl-10H-phenoxaphosphine
THE TITLE COMPOUND (SYSTEMATIC NAME 3,6-dimethyl-10-p-tolyl-9-oxa-10-phosphaanthracene), C(21)H(19)OP, is a precursor for the preparation of a bidentate xanthene-based ligand, in which the dihedral angle between the toluene ring and the phenoxaphosphine ring system is 83.26 (3)°. The geometry at the P atom is pyramidal, resulting in a longer C-P bond length as compared to the two ring C-P bonds.
متن کاملDiethyl 2,6-dimethyl-4-p-tolyl-1,4-dihydropyridine-3,5-dicarboxylate
In the title compound, C(20)H(25)NO(4), the 1,4-dihydro-pyridine ring adopts a flattened-boat conformation and forms a dihedral angle of 89.77 (8)° with the benzene ring. Inter-molecular N-H⋯O hydrogen bonds result in the formation of extended chains parallel to the b axis.
متن کامل(E)-3,5-Dimethyl-1-p-tolyl-4-(p-tolyldiazenyl)-1H-pyrazole
There are two independent mol-ecules, A and B, in the asymmetric unit of the title compound, C(19)H(20)N(4), in each of which the N=N double bond has an E conformation. The dihedral angles between the pyrazole ring and the p-tolyl rings in the 1- and 4-positions are 22.54 (8) and 35.73 (7)°, respectively, in mol-ecule A. The corresponding dihedral angles in mol-ecule B are 28.13 (8) and 22.18 (...
متن کاملp-Tolyl bis(p-tolylamido)phosphate
In the title compound, C(21)H(23)N(2)O(2)P, the P atom exhibits tetra-hedral coordination; the P-N bond lengths are relatively short [1.6297 (13) and 1.6424 (13) Å]. In the crystal, adjacent mol-ecules are linked by N-H⋯O hydrogen bonds into a zigzag chain running along the c axis.
متن کامل5-p-Tolyl-1H-tetrazole
The title compound, C(8)H(8)N(4), possesses crystallographic mirror symmetry, with four C atoms lying on the reflecting plane, which bis-ects the phenyl and tetra-zole rings. It is composed of a planar r.m.s. deviation (0.0012 Å) tetra-zole ring which is nearly coplanar with the benzene ring, the dihedral angle being 2.67 (9)°. In the crystal, symmetry-related mol-ecules are linked by inter-mol...
