AbstractIn the title compound, [Na4(C8H16BO 4)4(C4H10O2)] n, there are two coordination types for the four independent Na + cations: two Na+ cations bond to six diolate O atoms [Na-O = 2.305 (2)-2.609 (2) Å], while the other two are five-coordinate via one 1,4-butanediol [2.289 (2) and 2.349 (3) Å] and four diolate O atoms [2.295 (2)-2.408 (2) Å]. Corresponding to this, there are three- and four-coordinate diolate O atoms, the latter bridging Na atoms. The 1,4-butanediol molecules lie on inversion centres. The boron stereochemistry shows minor local perturbations from its usual tetrahedral state [B-O = 1.457 (4)-1.503 (4) Å]. The resulting polymer packs as sheets parallel to the (101̄) plane crosslinked by the butanediol molecules. The structure was solved using data from a multiple crystal. © 2005 International Union of Crystallography.
