Abstract: | The title complex, Zn2(C13H19N2O)2Cl2]·2C3H6O, resides on a crystallographic inversion center. The two ZnII centers bridged by the phenoxo groups are in pentacoordinated distorted square‐pyramidal coordination environments with an intramolecular Zn?Zn distance of 3.175 (3) Å. The mesocyclic ligand takes a boat–chair conformation and an H atom from the 1,5‐diazacyclooctane ring effectively blocks the axial coordination site opposite the Cl ligand to form the ZnN2O2Cl geometry. The crystal structure is stabilized by a N—H?O hydrogen bond between the amino group and an acetone molecule. |
