title: Poly[μ(4)-glutarato-di-μ(3)-glutarato-bis-(1,10-phenanthroline)diyttrium(III)].
abstract: In the title complex, [Y(2)(C(5)H(6)O(4))(3)(C(12)H(8)N(2))(2)](n), three glutarate groups and two 1,10-phenanthroline mol-ecules surround the two Y(III) ions. Both Y(III) ions are coordinated by two N atoms from the 1,10-phenanthroline, seven O atoms from five glutarate groups in a distorted tricapped trigonal-prismatic geometry. The Y(III) ions are bridged by glutarate ligands in three modes, forming a layered, polymeric structure. The resulting layers are assembled by π-π stacking inter-actions [centroid-centroid distances = 3.740 (3) and 3.571 (3) Å] into a three-dimensional supra-molecular architecture.
