Abstract: The reaction of hydroxylamine hydrochloride with isatin in ethanol, catalysed with HCl and neutralized with Na₂CO₃, yielded the one-dimensional coordination polymer, catena-poly[[[aquasodium]-di- [mu] -aqua-[aquasodium]-bis( [mu] -2-oxoindoline-2,3-dione 3-oximato)] tetrakis(oxoindoline-2,3-dione 3-oxime)], {[Na(C₈H₅N₂O₂)(H₂O)₂]·2C₈H₆N₂O₂}_n. The Na^I atom has a six-coordinate distorted-octahedral environment. Isatine-3-oximate O atoms and water molecules bridge adjacent Na atoms, forming a one-dimensional polymeric structure parallel to [100]. Each isatine-3-oxime dimerizes through N-HO interactions and in addition each oxime is linked to a coordination polymer. Thus, coordination polymers are linked by O-HO and O-HN interactions from isatine-3-oxime dimers, building a two-dimensional network parallel to [110].
