Rods of 5NICz molecules connected by C—H⋯N interactions (dotted lines) extending along [010] in the (a) LT and (b,c) HT polymorphs. Note that in the HT polymorph there are two kinds of rods, whereas in the LT polymorph all rods are related by symmetry. C and N atoms are represented by grey and blue ellipsoids, respectively, drawn at the 50% probability levels, H atoms by white spheres of arbitrary radius. Pseudo (a) and crystallographic (b,c) 21 screw axes are indicated using the usual symbol (Hahn & Aroyo, 2016BB10).
