Rhodium trichloride and its various hydrates can be considered the default halides of rhodium. By contrast, its lighter congener cobalt does not form a stable trichloride, mainly being available as cobalt(II) chloride. Anhydrous rhodium chloride is a dense red-brown solid.
Organorhodium chemistry is the chemistry of organometallic compounds containing a rhodium-carbon chemical bond, and the study of rhodium and rhodium compounds as catalysts in organic reactions. [ 1 ] Stable organorhodium compounds and transient organorhodium intermediates are used as catalyst such as in olefin hydroformylation , olefin ...
Dichlorotetrakis(pyridine)rhodium(III) chloride is the chloride salt of the coordination complex with the formula [RhCl 2 (pyridine) 4] +. Various hydrates are known, but all are yellow solids. The tetrahydrate initially crystallizes from water. [1] The tetrahydrate converts to the monohydrate upon vacuum drying at 100 °C.

The compound is prepared by the reaction of rhodium trichloride trihydrate and pentamethylcyclopentadiene in hot methanol, from which the product precipitates: [1] 2 C 5 (CH 3) 5 H + 2 RhCl 3 (H 2 O) 3 → [(C 5 (CH 3) 5)RhCl 2] 2 + 2 HCl + 6 H 2 O. It was first prepared by the reaction of hydrated rhodium trichloride with hexamethyl Dewar ...
Rhodium carbonyl chloride is an organorhodium compound with the formula Rh 2 Cl 2 (CO) 4. It is a red-brown volatile solid that is soluble in nonpolar organic solvents. It is a precursor to other rhodium carbonyl complexes, some of which are useful in homogeneous catalysis.
Lanthanide trichloride, LnCl 3, a class of chemical compound composed of a lanthanide atom and three chloride atoms. Lawrencium trichloride , LrCl 3 , a compound synthesised in 1969 expected to follow other actinide trichlorides.
Rhodium is a hard, silvery, durable metal that has a high reflectance. Rhodium metal does not normally form an oxide, even when heated. [25] Oxygen is absorbed from the atmosphere only at the melting point of rhodium, but is released on solidification. [26] Rhodium has both a higher melting point and lower density than platinum.
