Abstract:We introduce two novel one-dimensional coordination polymers (CPs) with helical arrangements based on copper-(II) and an achiral Schiff base ligand, [Cu(L)(DMF)(X)] n (X = NO 3 − (1) and Cl − (2)), where L = 2-{[(pyridin-3-yl)imino]-methyl}phenol. Both structures crystallize in an orthorhombic unit cell with a P2 1 2 1 2 1 space group. In both compounds, unconventional noncovalent interactions are fundamental for the structural features, modulating the dihedral angle ca. 70°between the two aromatic rings that … Show more
