In the title spiro compound, C(25)H(22)N(4)S, the planar quinoxaline (r.m.s. deviation = 0.070 Å) and planar thia-diazole (r.m.s. deviation = 0.060 Å) ring systems share a common C atom; their mean planes are aligned at 89.7 (1)°. The thia-zole ring possesses two aromatic ring substituents and is nearly coplanar with these rings [the dihedral angles between… (More)
In the title compound, C(23)H(17)NO(3)S, the thio-phene and isoxazole rings each have an envelope conformation with the spiro C atom linking them forming the flap of the envelope in each case. The dihedral angle between the mean planes of the benzothio-phene ring and isoxazole rings is 81.35 (7)°. In the crystal, an inter-molecular C-H⋯O hydrogen bond links… (More)
The seven-membered ring in the title compound, C(20)H(19)N(3)O(3), adopts a boat conformation with the two phenyl-ene C atoms representing the stern and the methyl-ene C atom the prow. The dihedral angle between the best plane through the seven-membered ring (r.m.s deviation = 0.358 Å) and the phenyl substituent is 55.8 (1)°. The two rings at either ends of… (More)
In the title compound, C(21)H(16)N(2)O(3), the fused-ring system (r.m.s. deviation = 0.067 Å) is slightly buckled at the carbonyl C atom of the anthracenyl ring system [deviation = 0.177 (1) Å] that is closer to an allyl substituent. The two allyl units lie on the same side of the fused-ring plane but are oriented in opposite directions, with N-C-C-C… (More)
The asymmetric unit of the title compound, C(10)H(6)N(2)O(2), contains two independent mol-ecules. The dihedral angles between the acetonitrile and the 1H-isoindole-1,3(2H)-dione units are 69.0 (7)° and 77.0 (5)° in the two mol-ecules. One of the two terminal N atoms is disordered over two positions in a 0.66 (8):0,34 (8) ratio. In the crystal structure,… (More)
The title compound C(20)H(20)O(2), has the exocyclic C=C double bond in an E configuration. The two benzene rings form a dihedral angle of 72.92 (6)°.
In the title compound, C(19)H(21)N(3)O(3)S, the C-SO(2)-NH-C torsion angle is 103.72 (11)°. The almost planar indazole ring [r.m.s. deviation = 0.0202 (14) Å] is twisted away from the methyl-benzene ring by 76.87 (7)°. The vinyl group is disordered over two orientations with site occupancies of 0.622 (10) and 0.378 (10). The S atom has a distorted… (More)
The structure of In(0.51)Fe(0.49)LiP(2)O(7) consists of a three-dimensional network constructed from (In(III)/Fe(III))O(6) octa-hedra and P(2)O(7) groups. Each M(III)O(6) octa-hedron is linked to six PO(4) tetra-hedra belonging to five different P(2)O(7) groups and shares two corners with the same P(2)O(7) group so as to build infinite chains or rather… (More)
The structure of the polymeric title compound, [CuCl(CH(4)N(2)S)(2)](n), has been redetermined to modern standards of precision with anisotropic refinement and location of the H atoms. The previous structure report [Spofford & Amma (1970 ▶). Acta Cryst. B26, 1474-1483] is generally confirmed to higher precision [typical Cu-S bond length s.u. values = 0.005… (More)
The indazole system in each of the two independent mol-ecules of the title compound, C(10)H(8)ClN(3)O(2), is planar (r.m.s. deviations = 0.005 and 0.005 Å). The nitro group is coplanar with the fused-ring system [dihedral angles = 1.3 (3) and 4.8 (3) Å].
