The crystal structure of [3-(1,4,7,10-tetraazacyclododecan-1-yl)propan-1-amine = L]zinc(II) bis(perchlorate), [ZnIIL](ClO4)2, was determined by the single-crystal X-ray diffraction method at 93.15 K. The titled complex crystallized in the orthorhombic space group P212121 and Z = 4 with a = 9.09970(10), b = 14.0995(2), c = 14.9908(2)Å, and V = 1923.34(4)Å3. The R1 [I > 2σ(I)] and wR2 (all data) values were 0.0214 and 0.0538, respectively, for all 3079 independent reflections. In the crystal structure, the zinc center is coordinated with the three secondary amines and one tertiary amine of the macrocycle and with the primary amine from the N-propylamino pendant arm, forming a distorted square pyramidal geometry.
