Assembly reaction of L-2 (5,8-dioxa-2,11-dithia[12]-m-cyclophane) with K2PtCl4 afforded a unique cyclic dimer complex [Pt-2(L-2)(2)Cl-4] (1) but its whole conformation is disordered 2 except two metal centers. Recrystallization of the same compound from dichloromethane afforded an isostructural product [Pt-2(L-2)(2)Cl-4]CH2Cl2 (2) but without such disorder. In 2, each Pt atom is four-coordinated in a square-planar environment with two S atoms from different two L(2)s and to two Cl- ions in a cis arrangement showing a basket-like conformation. Very interestingly, one dichloromethane molecule found in the cyclic dimmer cavity stabilizes the whole structure of 2 by hydrogen bonds.
