title: Bis{N-methyl-N'-[1-(pyridin-2-yl)ethyl-idene]ethane-1,2-diamine}-zinc bis-(perchlorate).
abstract: The title mononuclear zinc(II) complex, [Zn(C(10)H(15)N(3))(2)](ClO(4))(2), was obtained by the reaction of 2-acetyl-pyridine, N-methyl-ethane-1,2-diamine and zinc perchlorate in methanol. The asymmetric unit of the complex contains two independent [Zn(C(10)H(15)N(3))(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)ethyl-idene]ethane-1,2-diamine Schiff base ligands in a distorted octa-hedral 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)°. The perchlorate anions are linked to the complex cations through N-H⋯O hydrogen bonds.
