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

ABSTRACT: The reaction of hydroxyl-amine hydro-chloride with isatin in ethanol, catalysed with HCl and neutralized with Na(2)CO(3), yielded the one-dimensional coordination polymer, catena-poly[[[aqua-sodium]-di-?-aqua-[aqua-sodium]-bis-(?-2-oxoindoline-2,3-dione 3-oximato)] tetra-kis-(oxoindoline-2,3-dione 3-oxime)], {[Na(C(8)H(5)N(2)O(2))(H(2)O)(2)]·2C(8)H(6)N(2)O(2)}(n). The Na(I) atom has a six-coordinate distorted-octa-hedral environment. Isatine-3-oximate O atoms and water mol-ecules 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].
