Abstract

Tris(guanidinium) hexachlororhodate(III) monohydrate, [C(NH2)3]3[RhCl6] · H2O (1 ) has been obtained by the reaction of rhodium(III) chloride with guanidine hydrochloride in hydrochloric acid solution. 1 crystallizes in the triclinic space group P1̅ (a = 7.6013(9) Å, b = 8.6912(10) Å, c = 15.956(2) Å, α = 93.177(10)°, β = 101.691(10)°, γ = 113.995(9)°, V = 931.8(2), Z = 2). Two crystallographically independent hexachlororhodate ions, three crystallographically independent guanidinium ions and one water molecule are linked by a complex framework of hydrogen bonds.
