Dichloro(O-ethyl 3-methylpyridine-2-carboximidic acid-kappa2N,N')copper(II).

ABSTRACT

In the title compound, [CuCl2(C9H12N2O)], the Cu(II) atom is coordinated by two Cl- anions and two N atoms of one O-ethyl 3-methylpyridine-2-carboximidic acid molecule in a slightly distorted square-planar geometry, with Cu-N distances of 2.0483 (17) and 1.9404 (18) A, and Cu-Cl distances of 2.2805 (10) and 2.2275 (14) A. In addition, each Cu(II) atom is connected by one Cl- anion and the Cu(II) atom from a neighbouring molecule, with Cu...Cl and Cu...Cu distances of 2.9098 (13) and 3.4022 (12) A, respectively, and, therefore, a centrosymmetric dimer is formed. Adjacent molecular dimers are connected by pi-pi stacking interactions between pyridine rings to form a zigzag molecular chain. The molecular chains are also enforced by N-H...Cl and C-H...Cl interactions.
