N2 - The title compound, [(H3NCH2CH2NH2)Zn{3O,O′,O′′-B12O18(OH)6-1O′′′}Zn(en)(NH2CH2CH2NH3)].8H2O (en = 1,2-diaminoethane) (1), was prepared as a crystalline solid in moderate yield from the reaction of B(OH)3 with [Zn(en)3][OH]2 in aqueous solution (15:1) ratio. The structure contains a neutral bimetallic complex comprised of a unusual dodecaborate(6-) anion ligating two [H3NCH2CH2NH2Zn(en)n]3+ centres in a monodentate (n =1) or tridentate (n = 0) manner.
