Bis{N-methyl-N′-[1-(pyridin-2-yl)ethylidene]ethane-1,2-diamine}zinc bis(perchlorate)

The title mononuclear zinc(II) complex, [Zn(C10H15N3)(2)](ClO4)(2), was obtained by the reaction of 2-acetylpyridine, N-methylethane-1,2-diamine and zinc perchlorate in methanol. The asymmetric unit of the complex contains two independent [Zn(C10H15N3)(2)](2+) cations and four perchlorate anions. The Zn-II atom in each complex cation is six-coordinated by two pyridine N, two imine N and two amine N atoms from two N-methyl-N '-[1-(pyridin-2-yl) ethylidene]ethane-1,2-diamine Schiff base ligands in a distorted octahedral geometry. The pyridine rings in each of the complex cations are approximately perpendicular to each other, making dihedral angles of 88.4(3) and 87.9(3)degrees. The perchlorate anions are linked to the complex cations through N-H center dot center dot center dot O hydrogen bonds
