Dichlorotetrakis(pyridine)rhodium(III) chloride is the chloride salt of the coordination complex with the formula [RhCl₂(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 hydrates of [RhCl₂(pyridine)₄]Cl are prepared by heating

The molecular complex RhCl₃(pyridine)₃ is an intermediate in the synthesis of [RhCl₂(pyridine)₄]Cl.[3]
