(2R,3R)-1-(4-Chloro-phen-yl)-2-[(S)-2-nitro-1-phenyl-eth-yl]-3-phenyl-pentan-1-one.

The title compound, C(25)H(24)ClNO(3), has three contiguous chiral centres. The absolute structure was determined by anomalous dispersion. The chloro-benzene ring is inclined to the two phenyl rings by 14.

Diacetonitrile-(3-{2-[8-(2-bromo-eth-oxy)-9,10-dioxoanthracen-1-yl-oxy]eth-yl}-1-(2-pyridyl-meth-yl)imidazolium)silver(I) bis-(hexa-fluorido-phosphate).

The title compound, [Ag(C(27)H(23)BrN(3)O(4))(CH(3)CN)(2)](PF(6))(2), is a mononuclear salt species in which the silver(I) atom is coordinated by one ligand and two acetonitrile mol-ecules and exhibits a distorted T-shaped coordination. The asymmetric unit contains one independent cation and two independent hexa-fluorido-phosphate anions, one of which is disordered over two positions in a 0.756 (11):0.
