Bis[2-(diphenyl­phosphanyl-κP)benzaldehyde]­iodidogold(I)

In the title compound, [AuI(C₁₉H₁₅OP)₂], the complete mol­ecule is generated by the application of twofold symmetry. The Au^I atom is in a trigonal–planar geometry within an IP₂ donor set with the greatest distortion seen in the P—Au—P angle [128.49 (3) °]. Close intra­molecular Au...O inter­actions [3.172 (3) Å] are observed. No specific inter­molecular inter­actions are noted in the crystal packing.

Methyl 3-[4-(4-nitro­benz­yloxy)phen­yl]propano­ate

The title compound, C₁₇H₁₇NO₅, crystallizes with two mol­ecules (A and B) in the asymmetric unit. The conformational structures of the two mol­ecules show small but significant differences in the dihedral angles between the two aryl rings with values of 18.8 (1)° for mol­ecule A and 7.5 (1)° for mol­ecule B. In mol­ecule A, the propano­ate group is twisted out of the plane of the benzene group [C_ar—C_ar—C—C torsion angle = −44.9 (2)°], while for mol­ecule B, this group lies closer to the plane [C_ar—C_ar—C—C torsion angle = 8.6 (3)°]. C—H...O inter­actions characterize the crystal-packing inter­actions in this compound.

Dicyclo­hexyl­ammonium (S)-2-azido-3-phenyl­propano­ate

The asymmetric unit of the title compound, C₁₂H₂₄N⁺·C₉H₈N₃O₂⁻, consists of two dicyclo­hexyl­ammonium cations linked to two (S)-2-azido-3-phenyl­propano­ate anions by four short N—H...O hydrogen bonds with N...O distances in the range 2.712 (3)–2.765 (3) Å. The dicyclo­hexyl­ammonium cations and the aryl and carboxyl­ate groups of the anion are related by a pseudo-inversion centre, with overall crystallographic inversion symmetry for the structure broken by the chirality of the α-C atoms of the anions.

1-[4-Chloro-3-(trifluoro­meth­yl)phen­yl]-4-phenyl-1H-1,2,3-triazole

In the title compound, C₁₅H₉ClF₃N₃, the phenyl and chloro-trifluoro­methyl benzene rings are twisted with respect to the planar triazole group, making dihedral angles of 21.29 (12) and 32.19 (11)°, respectively. In the crystal, the mol­ecules pack in a head-to-tail arrangement along the a axis with closest inter-centroid distances between the triazole rings of 3.7372 (12) Å.
