N2 - The title compound, cis-[Rh(biq)2Cl2] Cl·3H2O (biq=2,2′-biquinoline) crystallized in the monoclinic space group P2 1 /n with a=11.231(2) Å, b=20.895(4) Å, c=14.081(3) Å, β=94.76(3)°, V=3293.0(11) Å3, D c=1.565 g cm-3, μ=0.806 mm -1, F(000)=1576 and Z=4. It contains a monomeric [Rh(biq) 2Cl2]+ cation, a chloride ion and three molecules of H2O. The rhodium(III) ion is hexa coordinated forming a distorted octahedral arrangement. The mean Rh(III)-N distance for the four Rh(III)-N bonds is 2.0625 Å. The two chloride atoms are bonded in a cis configuration [Rh(III)-Cl bond distances are 2.329(3) and 2.341(4) Å]. The structure shows a curling stacks of cationic complexes interacting via offset-face-to-face (OFF) π-π aryl interaction motif. Water molecules and chloride ions are hydrogen bonded (H2O⋯H-OH and Cl⋯H-OH) and links the curling stacks by hydrogen bonding via Rh-Cl⋯H-OH interactions.
