The self-assembly between a water-soluble bis-bidentate ligand L18w and Co­(II) salts in water affords three high-spin Co­(II) products: a dinuclear meso-helicate [Co2(L18w)3]­X4; a tetrahedral cage [Co4(L18w)6]­X8; and a dodecanuclear truncated-tetrahedral cage [Co12(L18w)18]­X24 (X = BF4 or ClO4)....
