Popis:	The synthesis and full characterization of the sterically demanding ditopic lithium bis(pyrazol-1-yl)borates Li2[p-C6H4(B(Ph)pzR2)2] is reported (pzR = 3-phenylpyrazol-1-yl (3Ph), 3-t-butylpyrazol-1-yl (3tBu)). Compound 3Ph crystallizes from THF as THF-adduct 3Ph(THF)4 which features a straight conformation with a long Li···Li distance of 12.68(1) A. Compound 3tBu was found to function as efficient and selective scavenger of chloride ions. In the presence of LiCl it forms anionic complexes [3tBuCl]− with a central Li-Cl-Li core (Li···Li = 3.75(1) A).
