A Hydrogen-Bonded [(Mercuracarborand-Water)2 -Benzene] π-Sandwich Complex.
Two cyclic Lewis acidic receptors, namely B-hexamethyl-9-mecuracarborand-3, [9,12-(CH3 )2 -C2 B10 H8 Hg]3 , each host a single water molecule. A benzene molecule is situated between the two complexed water molecules in a sandwich fashion that suggests there is O-H⋅⋅⋅π hydrogen bonding.
