|Title:||Novel luminescent tetranuclear and pentanuclear copper(I)-dithiolates||Authors:||Xu, H.
|Issue Date:||28-Jul-2003||Citation:||Xu, H.,Yip, J.H.K. (2003-07-28). Novel luminescent tetranuclear and pentanuclear copper(I)-dithiolates. Inorganic Chemistry 42 (15) : 4492-4494. ScholarBank@NUS Repository.||Abstract:||Tetranuclear [Cu4(μ2-dppm) 3(μ2-μ2- NS2)(μ2-μ4-NS2)] (1) and pentanuclear [Cu5(μ2-dppm) 4(μ3-μ-3- NS2)2]PF6 (2·PF6) (dppm = bis(diphenylphoshino)methane, NS2 2- = 1,8-naphthalenedithiolate) were synthesized from the reactions between NS2 2- and [Cu2(μ2-dppm) 2(CH3CN)2](PF6)2. Compound 1 features a square Cu4 core capped by a 5-coordinate S atom while 2·PF6 exhibits an unprecedented square planar Cu5 core. Both complexes display dual emissions at 480 and 620 nm which arise from ligand-centered nπ* and ligand-metal charge-transfer excited states, respectively.||Source Title:||Inorganic Chemistry||URI:||http://scholarbank.nus.edu.sg/handle/10635/94387||ISSN:||00201669|
