N1,N2-Di(pyridin-4-yl)oxalamide (cas: 53118-43-7) belongs to amides. Because of the greater electronegativity of oxygen, the carbonyl (C=O) is a stronger dipole than the N–C dipole. The presence of a C=O dipole and, to a lesser extent a N–C dipole, allows amides to act as H-bond acceptors. The presence of the amide group –C(=O)N– is generally easily established, at least in small molecules. It can be distinguished from nitro and cyano groups in IR spectra. Amides exhibit a moderately intense νCO band near 1650 cm−1. By 1H NMR spectroscopy, CONHR signals occur at low fields. In X-ray crystallography, the C(=O)N center together with the three immediately adjacent atoms characteristically define a plane.SDS of cas: 53118-43-7

The reaction of Cu(NO3)2·3H2O with N1,N2-di(pyridin-4-yl)oxalamide (L) and KSCN in the presence of DMF by the layering method gives rise to a new complex [Cu(L2)(SCN)2(DMF)2]n (1). Complex 1 was characterized by single-crystal and powder x-ray diffraction, IR spectroscopy, and elemental and thermogravimetric analyses. It crystallizes in the triclinic system with space group P1̅ and shows a chain structure. Delicate N-H···O hydrogen bonding exists in individual units, and adjacent chains are linked by intermol. interactions, resulting in an extended 2D network. This study involved multiple reactions and reactants, such as N1,N2-Di(pyridin-4-yl)oxalamide (cas: 53118-43-7SDS of cas: 53118-43-7).
