【 摘 要 】

We present here three compounds consisting of pyridinium or morpholinium hydrogen oxalates, each displaying different hydrogen-bonding motifs, resulting in chains for 4-(di­methyl­amino)­pyridinium hydrogen oxalate 0.22-hydrate, C7H11N2+·C2HO4−·0.22H2O (1), dimers for 4-tert-butyl­pyridinium hydrogen oxalate, C9H14N+·C2HO4− (2), and chains for morpholin­ium hydrogen oxalate, C4H10NO+·C2HO4− (3).
