Abstract

As ditopic host system incorporating hard base and soft base domains, an 18-membered (L1 and a 20-membered (L2)2-4 N2O2S2-macrocycles and their supramolecular complexes are reported. The reactions of ZnBr2 and CdBr2 with L1 afforded mononuclear complexes [Zn(L1)][ZnBr4] (1) and [Cd(L1)Br2] (2), respectively. When HgBr2 was used, a dinuclear complex [Hg2(L1)Br4] (3) was obtained. While, Hg(NO3)2 gave a 1-D CP {[Hg2(L1)](NO3)2}n (4, see below) as a first example of the infinite macrocyclic mercury(I) complex. The reaction of a mixture of ZnBr2 and CdBr2 afforded two solubility-dependent Cd(II) complexes (2 and 5) including a half dumbbell-type complex [Cd(L1)(μ-Br)(CdBr3)] (5). Interestingly, one-pot reaction of a mixture of CdBr2 and HgBr2 afforded a dumbbell-type heterometallic product [(CdL1)2(μ-Hg2Br6)](Hg2Br6) (6, see below). In the equimolar reaction of L2, AgPF6 afforded a typical endocyclic complex [Ag(L2)(PF6)] (7). However, the use of three equivalents or above amount of AgPF6, gave an endo/exocyclic 1-D CP {[Ag4(L2)2](PF6)4∙2CH2Cl2}n (8a, see below). Upon removal of the lattice dichloromethane molecules in the ambient condition, conversion of the coordination geometry of the exo-Ag atom from linear (8a) to trigonal plane (8b, {[Ag4(L2)2(PF6)2](PF6)2}n) as well as sliding of the 1-D chains were observed in an SCSC manner.
