title: Bis[mu-P,P'-methylenebis(diisopropyl phosphonate)-kappa3O,O':O]bis[chlorolithium(I)]: a centrosymmetric dimer of lithium chloride with terminal chloride anions.
abstract: The molecule of the title dimeric compound, [Li(2)Cl(2)(C(13)H(30)O(6)P(2))(2)] or [LiCl([((i)PrO)(2)P(O)](2)CH(2))](2), lies about an inversion center and features tetrahedrally coordinated Li atoms. The neutral ligands each chelate to one metal center and bridge to the other center through P=O units. Unusually for lithium chloride complexes, the Cl- ions are in terminal rather than bridging positions. Principal dimensions include Li-O(four-membered ring) = 1.959 (3) and 2.056 (3) A, Li-O(phosphonate ring) = 1.929 (3) A, and Li-Cl = 2.293 (3) A.
