A solvent stabilized cyclic dimer complex of platinum(II) with S2O2 macrocycle

Assembly of L2 (5,8-dioxa-2,11-dithia[12]-m-cyclophane) with K2PtCl4 followed by recrystallization from CH2Cl2 afforded a cyclic dimer complex [Pt2(L2)2Cl4]CH2Cl2 (2). Interestingly, one CH2Cl2 molecule found in the cyclic dimmer cavity stabilizes the whole structure of 2 by hydrogen bonds.
