A one-dimensional coordination polymer constructed from isatine-3-oximate and sodium

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-μ-aqua-[aqua­sodium]-bis­(μ-2-oxoindoline-2,3-dione 3-oximato)] tetra­kis­(oxoindoline-2,3-dione 3-oxime)], {[Na(C8H5N2O2)(H2O)2]·2C8H6N2O2}n. The NaI 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—H⋯O interactions and in addition each oxime is linked to a coordination polymer. Thus, coordination polymers are linked by O—H⋯O and O—H⋯N interactions from isatine-3-oxime dimers, building a two-dimensional network parallel to [110].

“…A search of SciFinder (SciFinder, 2018) revealed a single report in the literature about the crystal structure of coordination compounds with isatin 3-oxime derivatives, i.e. the one-dimensional coordination polymer, catena-poly-[[[aquasodium]-di--aqua-[aquasodium]-bis(-2-oxoindoline-2,3-dione 3-oximato)] tetrakis(oxoindoline-2,3-dione 3-oxime)] (Barreto Martins et al, 2011). For that complex, the Na cations shows an octahedral coordination environment builded by the anionic form of the isatin 3-oxime and water molecules (Fig.…”
