catena-Poly[[diaqualithium(I)]-mu-[9H-purine-2,6(1H, 3H)-dionato-O2:N7]].
In the title compound, [Li(C(5)H(3)N(4)O(2))(H(2)O)(2)](n), the coordinate geometry about the Li(+) ion is distorted tetrahedral and the Li(+) ion is bonded to N and O atoms of adjacent ligand molecules forming an infinite polymeric chain with Li-O and Li-N bond lengths of 1.901 (5) and 2.043 (6) A, respectively. Tetrahedral coordination at the Li(+) ion is completed by two cis water molecules [Li-O 1.985 (6) and 1.946 (6) A]. The crystal structure is stabilized both by the polymeric structure and by a hydrogen-bond network involving N-H.O, O-H.O and O-H.N hydrogen bonds.
