A novel supramolecular adduct [(H3O)2 (PtCl6)]3 (C42H42N28O14)2·H2O (1) was synthesized by mixing [PtCl6]2− and cucurbit [7] uril in solution of hydrochloric acid. The crystal structure was determined by single crystal X-ray diffraction analysis. The crystal belongs to orthorhombic system and space group F dd2 with cell dimensions:a=4. 705 33 (5) nm,b=7. 153 80 (6) nm,c=1. 894 61 (2) nm,Z=16,V=63, 7744 (11) nm3,D c =1.534 g/cm3, μ=3. 007 mm−1,F(000)=29 120,R 1=0.070 7,wR 2=0. 169 2. In crystal, the cucurb [7] uril molecules from two zig-zag chains.
