Catena-Poly[[[iodidocopper(I)]-{?-N-[(pyridin-2-yl-?N)methyl-idene]pyridin-3-amine-?(2)N(3):N(1)}] acetonitrile hemisolvate].

ABSTRACT: In the asymmetric unit of the title polymeric complex, {[CuI(C(11)H(9)N(3))]·0.5CH(3)CN}(n), there are two Cu(I) atoms, two N-[(pyridin-2-yl-?N)methyl-idene]pyridin-3-amine (PyPy) ligands and two I atoms. Both Cu(I) atoms have a distorted tetra-hedral geometry, each being coordinated by one I atom, two N atoms of one PyPy ligand and one N atom from an adjacent PyPy ligand. In the crystal, infinite helical chains of [Cu(2)(PyPy)(2)](n) are formed propagating along the b axis. These chains are linked via weak C-H?I hydrogen bonds and ?-? stacking inter-actions [shortest centroid-centroid distance = 3.2727?(14)?Å]. During the refinement, electron-density peaks were located that were believed to be highly disordered solvent mol-ecules (possibly acetonitrile). The SQUEEZE option in PLATON [Spek (2009 ?). Acta Cryst. D65, 148-155] indicated there were solvent cavities with a total volume of 196?Å(3) containing approximately 60 electrons per unit cell, which equated to one mol-ecule of acetonitrile per asymmetric unit.
