[1-(Anthracen-9-ylmeth-yl)-1,4,7,10-tetra-aza-cyclododeca-ne]chlorido-zinc(II) nitrate.

In the title salt, [ZnCl(C(23)H(30)N(4))]NO(3), the central Zn(II) atom of the complex cation is coordinated in a square-pyramidal arrangement by four nitro-gen atoms from cyclen (1,4,7,10-tetra-aza-cyclo-dodeca-ne) in the basal plane and one chlorido ligand in the apical position. The anthracene group attached to cyclen contributes to the crystal packing through inter-molecular T-shaped π inter-actions. Additionally, the nitrate anion participates in inter-molecular N-H⋯O hydrogen bonds with cyclen.
