Crystal structure of a three-dimensional neodymium(III) coordination polymer, [Nd(2)(H(2)O)(6)(glutarato)(SO(4))(2)]( n )

A three-dimensional coordination polymer, poly[hexa­aqua­(μ(4)-glutarato)bis(μ(3)-sulfato)­dineodymium(III)], [Nd(2)(glutarato)(SO(4))(2)(H(2)O)(6)]( n ) (glutarato(2–) = C(5)H(6)O(4) (2–)), 1, consisting of cationic {Nd(2)(H(2)O)(6)(SO(4))(2)}( n ) (2n+) layers linked by bridging glutarate ligands, was synthesized by the microwave-heating technique within few minutes. The crystal structure of 1 consists of two crystallographically independent TPRS-{Nd(III)O(9)} (TPRS is tricapped trigonal–prismatic geometry) units that form an edge-sharing dinuclear cluster inter­connected to neighbouring dimers by the μ(3)-SO(4) (2–) anions, yielding a cationic two-dimensional {Nd(2)(H(2)O)(6)(SO(4))(2)}( n ) (2n+) sheet. Adjacent cationic layers are then linked via the μ(4)-glutarato(2–) ligands into a three-dimensional coordination network. Strong O—H⋯O hydrogen bonds are the predominant inter­action in the crystal structure.
