The lithium tetrakis(methimazolyl)borate Li[Bmt4] is accessible from the reaction of Li[BH4] with four equivalents of methimazole. The crystal structure of Li[Bmt4] supported by four water molecules is described. Reaction of Li[Bmt4] with [Ru(p-cymene)Cl2]2 and subsequent treatment with NH4PF6 in CH3CN results in the formation of the complex [Ru(p-cymene)(Bmt4)][PF6]. In addition, we report the result of the X-ray structure analysis of the chiral Ru complex [Ru(p-cymene)(Bmt4)][PF6].
