Abstract
Bis(diisopropylammonium) hexachloroiridate(IV), [{(H3C)2CH}2NH2]2[IrCl6], crystallizes in the monoclinic centrosymmetric space group P21/c with two crystallographically independent [IrCl6]2− anions, each located on a center of symmetry, and two crystallographically independent diisopropylammonium cations in general positions. Weak hydrogen bonding occurs between the cations and anions to form layers parallel to the bc plane. Each layer is built by annealed 24-membered rings that can be classified according to Etter's nomenclature as R88(24). The structural relationship between K3[IrCl6] and the title compound shows that a replacement of three potassium cations by two diisopropylammonium cations leads to a layered structure. The hydrophilic layers that are dominated by hexachloroiridate(IV) anions are separated by lipophilic regions in the planes at x = 1/4 and x = 3/4.
