Abstract
The structure of K2[RhCl5(H2O)] has been established by X-ray crystallography. It crystallizes in the orthorhombic space groupPcmn, with cell dimensionsa=7.065(1),b=9.453(1),c=13.567(1) Å,V=906.1(3) Å3,Z=4,M r =376.4,D x =2.76 g cm−3,F(000)=712,T=293 K. The final wasR=0.046. The rhodium atom has a distorted octahedral coordination involving five chlorine atoms and an oxygen of the water molecule with Rh, O, and three chlorine atoms on the mirror plane. Rh-Cl distances range from 2.284(7) Å to 2.345(7) Å. The Cl(4)⋯O intermolecular distance, 3.140(12) Å indicates strong hydrogen bonding between oxygen and chlorine atoms of the neighboring octahedra.
