(a) ORTEP diagram of L¹•2DMSO•CH₃OH with 30% thermal ellipsoids showing H-bonds between L¹ and solvent guest molecules; a disordered DMSO molecule and hydrogen atoms not involved in H-bonds are omitted for clarity. The O(1S)⋯N(1), O(1S)⋯N(2), O(1S)⋯N(3) and O(2S)⋯N(5), O(2S)⋯N(6) distances are 2.731(5), 3.202(5), 2.786(5) and 3.229(6), 2.767(6) Å, respectively;(b) Space-filling model of L¹ found in a L¹•2DMSO•CH₃OH showing the “O” conformation in the solid state.
