intermolecular hydrogen bonds between an amide and carbonyl [N–H···O = 2.8206(11) Å and 2.8637(11) Å] and two intermolecular hydrogen bonds between an amide and ether [N–H···O = 2.9570(11) Å and 3.0067(11) Å]. There are two intramolecular hydrogen bonds between amide and ether oxygens [N–H···O = 2.589(3) Å and 2.623(4) Å] in II. Molecule III has a mixture of intramolecular hydrogen bonds between an amide
