The imidazolium nitrates [ImH](NO 3 ) ( 1 ) and [ImBr](NO 3 ) ( 2 ) are obtained from the corresponding bromides [ImH]Br ( 3 ) and [ImBr]Br ( 4 ) and AgNO 3 in excellent yields (Im = 2, 3‐dihydro‐1, 3‐diisopropyl‐4, 5‐dimethylimidazol‐2‐ylidene). The crystal structures of 1 and 2 consist of infinite linear chains of ions linked by H···O and Br···O contacts. In addition, stacks consisting of imidazolium and nitrate ions in the sequence ImBr/NO 3 /ImBr/NO 3 ··· with parallel orientation of their plains are detected in 2 . The crystal structure of 3 is also reported.
