Abstract: Key indicators: single-crystal X-ray study; T = 298 K; mean (C-C) = 0.004 Å; R factor = 0.049; wR factor = 0.153; data-to-parameter ratio = 30.1.In the title hydrate, (C 4 H 12 N 2 )[Co{B 6 O 7 (OH) 6 } 2 ]Á6H 2 O, both the dication and dianion are generated by crystallographic inversion symmetry. The Co 2+ ion in the dianion adopts a fairly regular CoO 6 octahedral coordination geometry arising from the two O,O 0 ,O 00 -tridentate ligands. In the crystal, the dianions and water molecules are linked by O-HÁ Á…
