The hydrogen-bonding capacity of the (nccm)− anion. (a) Two kinds of mutual interactions marked in black and red and bonding with NH4+ cations marked in blue; (b–d) three types of supramolecular synthons identified for the the title compound taking into account a set of strongest interactions: ammonium/nitroso chain (b), amide/amide chains (c) and mutual amide/nitrile bonding (d). |
