[(Z)-O-Ethyl N-phenyl-thio-carbamato-κS](tricyclo-hexyl-phosphine-κP)gold(I): a monoclinic polymorph
Abstract:
The title compound, [Au(C(9)H(10)NOS)(C(18)H(33)P)], represents a monoclinic polymorph to complement a previously reported triclinic (P) polymorph [Hall et al. (1993 ▶). Aust. J. Chem.46, 561-570 (unit-cell data only)]. The Au(I) atom is coordinated within an S,P-donor set that defines a slightly distorted linear geometry [S-Au-P = = 175.43 (3)°], with the distortion due in part to a close intra-molecular Au⋯O contact [3.036 (2) Å]. In the crystal structure, mol-ecules are arranged into supra-molecular chains along the b axis mediated by C-H⋯π inter-actions.

Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the unhybridized p...
