Interaction of silver(I) and copper(I) with an O2S2-macrocycle – A comparative structural study
摘要:
The 14-membered O2S2-macrocycle L reacts with AgPF6 in acetonitrile/dichloromethane (1: 1) to yield the cyclic, double S-Ag-S bridged complex, [Ag2L2(CH3CN)(4)](PF6)(2) (2), in which each Ag(I) is bound to two exo-oriented S donors arising from different macrocycles to form a 12-membered, di-Ag metallacycle. Two PF6 ions form weak intramolecular contacts [Ag center dot center dot center dot F, 2.925(2)angstrom] between the Ag centres in a bridging bidentate fashion. The coordination sphere of each Ag is completed by two weakly bound acetonitrile molecules. The respective macrocyclic ligands are arranged trans to the mean plane through the metallacycle. When the above synthetic procedure was repeated employing methanol/dichloromethane (1:1) as solvent, a complex of type [Ag2L2](PF6)(2) (3) was obtained whose structure incorporates a similar 12-membered metallacycle but with the respective macrocyclic rings now oriented towards the same side of the metallacyclic plane. The reaction of L with AgCF3SO3 yields [Ag2L2(CF3SO3)(2)]center dot 2CH(3)CN (4) whose structure resembles that of [Ag2L2(CH3CN)(4)] (PF6)(2) (2); each complex unit incorporates a di-Ag(I) 12-membered metallacycle, with symmetrical bridging bidentate CF3SO3 ions weakly linking Ag centres. Long Ag1 center dot center dot center dot Ag1C contacts are present between pairs of complex units. Reaction of Cu(CH3CN)(4)PF6 (one equiv.) with L in methanol/dichloromethane (1: 1) resulted in isolation of [CuL2]PF6 (5) incorporating a distorted tetrahedral S-4-coordination sphere, with each macrocycle binding as a bidentate ligand via its two (exo-orientated) S atoms. In contrast, reaction of [Cu(CH3CN)(4)]PF6 (two equiv.) with L in either acetonitrile/dichloromethane (1: 1) or methanol/dichloromethane (1: 1) yielded [Cu2L3]PF6 (6) in which the Cu(I) centres are bound exo to the macrocyclic cavity by individual S-donors from one L, with the coordination sphere of each Cu(I) completed by out-of-plane binding of the S2O donors from a second L.

(L1: 15-membered, L2: 14-membered analogue) were employed as soft donorligands towards palladium(II). Two-step approach via reaction of 1:1-type complex, [cis-Cl2(L1)Pd], with L2 through a successive treatment of AgClO4 has led to the isolation of a co-crystallised bis(O2S2 macrocycle) palladium(II) complex 1, [Pd(L1)2] · [Pd(L2)2]}(ClO4)4 containing two different homo-ligand bis(O2S2 macrocycle)

Two isomeric S2O2 macrocycles (L1 and L2) with a 14-membered cavity have been synthesised as a model system with different binding modes. Self-assembly reactions of L1 and L2 with silver perchlorate afford the respective ligand-directed cyclic oligomer complexes with different shapes: a poly(bicyclic dimer) (1) and a discrete cyclic tetramer (2). The formation of these supramolecular complexes is discussed
