2,4,8,10,13-Pentamethyl-6-phenyl-13,14-dihydro-12H-6λ5-dibenzo[d,i][1,3,7,2]dioxazaphosphecin-6-thione
In the title compound, C(25)H(28)NO(2)PS, the cyclo-decene ring exhibits a crown conformation. The two dimethyl-benzene rings which are fused symmetrically on either side of the ten-membered ring, make dihedral angles of 20.2 (1) and 18.0 (1)°. The phenyl ring substituted at P is perpendicular to the heterocyclic ring, making a dihedral angle of 88.4 (1)°. The crystal structure is stabilized by...

The asymmetric unit of the title compound, C(17)H(14)O(6)S, contains four crystallographically independent mol-ecules in which the pyran-one units are essentially planar, with maximum deviations of 0.016 (2), 0.019 (2), 0.025 (2), 0.014 (2), 0.020 (2), 0.010 (2), 0.003 (2) and 0.012 (2) Å. One of the thio-phene rings is disordered over two positions, with an occupancy ratio of 0.739 (4):0.261 (...
متن کامل(E)-3-(2-Chloro-6-methyl-3-quinolyl)-1-(2,3-dihydro-1,4-benzodioxin-6-yl)prop-2-en-1-one
In the title mol-ecule, C(21)H(16)ClNO(3), the quinoline and benzene rings are inclined at 56.96 (6)° with respect to each other and the dioxine ring is in a twist-chair conformation. The structure is devoid of any classical hydrogen bonds. Rather weak inter-molecular hydrogen-bonding inter-actions of the types C-H⋯N and C-H⋯O are present, consolidating the crystal structure.

In the title compound, C(19)H(17)N(2)O(3)P, the six-membered 1,3,2-oxaza-phospho-rine ring adopts a twist-boat conformation with the phosphoryl O atom in an equatorial position. The P=O(oxide) bond length is 1.457 (1) Å and the average value of the P-O distances is 1.588 Å. The crystal structure is stabilized by C-H⋯O and C-H⋯π inter-actions.

In the title compound, C(19)H(17)N(2)O(2)P, the six-membered 1,3,2-oxaza-phosphinine ring adopts a boat conformation with the phosphoryl O atom in an equatorial position. The dihedral angle between the 6-methyl-2-pyridyl and phenyl groups is 75.5 (1)°. These substituents are trans to each other, and are oriented at angles of 57.2 (1) and 74.8 (1)°, respectively, to the benzene ring. The crystal...
