Notes:
Two pentahalo(N-donor)bismuthate(III) salts, bis[hydrogen bis(4-picoline)(1+)] pentabromo(4-picoline-N)bismuthate(III), (C12H15N2)2[BiBr5(C6H7N)], (I), and bis(pyridinium) pentachloro(pyridine-N)bismuthate(III), (C5H6N)2[BiCl5(C5H5N)], (II), are described which show modest deviations from octahedral geometry at bismuth. In (I), the cations comprise two 4-picoline molecules sharing a proton and in (II), pyridinium cations are present. The anion in (I) has twofold and that in (II) has mirror crystallographic symmetry. Both structures show a layered packing formed by the anions with the cations between the layers. Ring–ring interactions seem important in (I), whilst in (II), N/C—H...Cl—Bi hydrogen bonding is abundant.
