Research output: Contribution to journalConference articlepeer-review


The [NH4+][Ni(dmit)2]3 complex, containing a macrocyclic molecule of 18-crown-6-ether (18C6), was obtained as [NH4+[18C6][Ni(dmit)2]3. This salt showed semiconducting behaviour with room temperature conductivity of 0.4 Scm-1. The crystal is composed of segregated non-uniform stack of Ni(dmit)2 and isolated ion-captured cavity of [NH4+][18C6]. The NH4+ ion was fully included in a cavity, and was tightly bounded through strong hydrogen bonds to the oxygen atoms of 18C6.
