Bis[2,2'-iminodipyridinium(1+)] Bis[-4-hydroxy-2,6-pyridinedicarboxylato(3 -)]bis[aquadibutyltin(IV)] Dihydrate

The water-coordinated Sn atom in the centrosymmetric title compound, (C₁₀H₁₀N₃)₂[Sn₂(C₇H₂NO₅)₂(C₄H₉)₄(H₂O)₂].2H₂O, is seven-coordinate in a trans-C₂SnNO₄ pentagonal bipyramidal geometry [C-Sn-C = 156.6 (1)°]. The dianion is linked to two planar 2,2'-iminodipyridinium(1+) cations through the lattice water molecules via the amino bridges [O_water

N_amino = 2.810 (5), O_water

O_hydroxy = 2.633 (4) and O_water

O_carbonyl = 2.927 (5) Å]. A weaker water-water interaction connects the ion pair into a linear helical chain.
