Abstract

Crystals of (HDABCO+)9(DABCO)[Ni(dmit)2]9·6CH3CN were shown to have a space group of R3[combining macron], a hexapetal flower-like channel of [Ni(dmit)2] anions, and a one-dimensional hydrogen bonding chain composed of protonated DABCO and CH3CN molecules. The crystals display antiferromagnetic and ferromagnetic interactions within and between hexamers, respectively, whereas the flexible DABCO-CH3CN array shows dielectric relaxation.
