[N,N'-Bis(4-chloro-phen-yl)pentane-2,4-diiminato]dicarbonyl-rhodium(I).

The title compound, [Rh(C(17)H(15)Cl(2)N(2))(CO)(2)], is a rhodium(I) derivative of a ß-diketiminato moiety. It is an example of a new type of ß-diketiminate derivative that has not yet been characterized via solid-state methods. The complex crystallizes with a distorted square-planar geometry about the Rh(I) atom (m symmetry). A weak inter-molecular C-H⋯O contact is observed.

(3,5,7-Tribromo-tropolonato-κO,O')tris-(triphenyl-phosphine-κP)silver(I).

The title compound, [Ag(C(7)H(2)Br(3)O(2))(C(18)H(15)P)(3)], a silver(I) derivative of 3,5,7-tribromo-tropolone, has three triphenyl-phosphine ligands coordinated to the silver centre, whereas the 3,5,7-tribromo-tropolonate anion coordinates as a bidentate ligand. The compound is an example of a five-coordinate silver complex containing a bidentate ligand.
