Tetramethyl 1,1,2-triphenyl-2H-1λ5-phosphole-2,3,4,5-tetracarboxylate
The title compound, C(30)H(27)O(8)P (1), was formed as one of two products {(1) and (2) [Krawczyk et al. (2010 ▶). Acta Cryst. E66 (cv2753)]} in the reaction of dimethyl acetyl-enedicarboxyl-ate with triphenyl-phosphine. The mol-ecule of (1) consists of a five-membered ring, in which the P atom is incorporated. One of the phenyl groups of the triphenyl-phosphine migrated to a vicinal C atom dur...
متن کامل2,3,5-Triphenyl-2H-tetrazol-3-ium iodide
The asymmetric unit of the title mol-ecular salt, C(19)H(15)N(4) (+)·I(-), contains four 2,3,5-triphenyl-2H-tetra-zol-3-ium cations and five iodide anions, with two of the latter lying on crystallographic inversion centres. In each cation, the tetra-zole ring is essentially planar (r.m.s. deviations = 0.004-0.007 Å). The dihedral angles between the tetra-zole ring and its three attached benzene...

In the title salt, C(19)H(15)N(4) (+)·C(24)H(20)B(-), the tetra-phenyl-borate anion is in a tetra-hedral geometry around the B atom [C-B-C angles of 107.10 (9)-111.79 (9)°]. In the cation, the tetra-zole ring makes dihedral angles of 3.04 (7), 51.75 (7) and 51.13 (7)° with the attached phenyl rings. In the crystal, C-H⋯π inter-actions link the cations and anions into ion pairs.

In the title compound, C(19)H(15)N(4) (+)·Br(-)·C(2)H(5)OH, the tetra-zole ring makes dihedral angles of 57.44 (9), 50.92 (9) and 4.65 (8)° with the attached phenyl rings. In the crystal, the cation and the anion are linked to each other by inter-molecular C-H⋯Br hydrogen bonds into an infinite chain along the b axis. The anion and the ethanol solvent mol-ecule are linked by an O-H⋯Br hydrogen ...
