Crystal structure of a supramolecular cation salt (adamantylammonium+)2(benzo[18]crown-6)2[Pd(dmit)2]2−(acetone)2

Single crystal of supramolecuar cation salt (adamantylammonium+)2(benzo[18]crown-6)2[Pd(dmit)2]2−(acetone)2 were synthesized by an electrochemical crystallization. In the crystal, two supramolecular cations and two acetones and one [Pd(dmit)2]2− dianion were crystallographically asymmetric. Molecular rotation of adamantyl groups was suggested from anisotropic thermal factors in the X-ray analysis at 173 K.
