چکیده
Four copper(II) complexes and one copper(I) complex with pyridine-containing pyridylalkylamide ligands N-(pyridin-2-ylmethyl)pyrazine-2-carboxamide (HL) and N-(2-(pyridin-2-yl)ethyl)pyrazine2-carboxamide (HL) were synthesized and characterized. The X-ray crystal structures of [Cu2(L )2(4,4ʹ-bipy)(OTf )2] (1, OTf = trifluoromethanesulfonate, 4,4ʹ-bipy = 4,4ʹ-bipyridine) and [Cu(L)(py)2]OTf·H2O (2, py = pyridine) revealed binuclear and mononuclear molecular species, respectively, while [Cu(L)(μ2-1,1-N3)]n (3), [Cu(L )(μ2-1,3-N3)]n (4), and [Cu(HL )Cl]n (5) are coordination polymer 1-D chains in the solid state.

The title compounds, C11H10N4O (HL1) and C11H10N4O (HL2), are pyridine 2-ylmethyl and 4-ylmethyl derivatives, respectively, of pyrazine-2-carboxamide. HL1 was measured at 153 K and crystallized in the monoclinic space group P21/c with Z = 4. There has been a report of the same structure measured at room temperature but assumed to crystallize in the triclinic space group P-1 with Z = 4 [Sasan et...
