Supramolecular self-assembly involving cooperative use of dative coordinate, secondary and hydrogen bonding in solid [(Me3Sn)3(μ-OH)2]+Br−

Trinuclear Sn3(μ-OH)2 moieties formed through coordinate dative bonds are associated into chains through secondary Sn⋯Br− interactions and further self-assembled in a three-dimensional network through O–H⋯Br− hydrogen bonds.
