Protonation of the 1,1-dithiolene ligands in the [Cu8(L)6]4- cubanes (L = [S2C:C(COOR)2]2-) and synthesis of the [Cu8(L)6-n(H-L)n]-(4-n) clusters. Synthesis and structural characterization of the [Cu10(H-L)6(L)2] decanuclear cluster

Abstract: tional parameters and their errors (Tables S2 and S7), thermal parameters (Tables S3 and S8), bond distances (Tables S4 and S9), bond angles (Tables S5 and S10), and electronic absorption spectral data (Table SI 1), and figures showing the full atomic number schemes for the monocations of I (Figure SI) and 2 (Figure S2) and the X-band ESR spectrum of [Re2Cl3(M-HN2C2Me2)(M-dppm)2(NCMe)]PF6 (Figure S3) (44 pages); tables of observed and calculated structure factors (82 pages). Ordering information is given on an… Show more

“…These shifts are attributed to the coordination of the bis(triphenylphosphine)copper(I) moiety to ligand 1a through the sulfur atoms. These observations are in agreement with previously reported palladium(II) coordination compounds 8,10 and copper(I) clusters …”

“…11 The 1,1-ethylenedithiolato ligands have also been used to stabilize unusually high oxidation states [12][13][14] or to facilitate the syntheses of clusters. [15][16][17][18][19][20][21] Most 1,1-ethylenedithiolato complexes are mononuclear 7-9,12-14, [22][23][24][25][26][27] although some polynuclear complexes [28][29][30][31] including clusters 15,18,19,[32][33][34][35][36][37] are known.…”

“…Most 1,1-ethylenedithiolato metal complexes are mononuclear, , although some homopolynuclear complexes with bridging or chelating 1,1-ethylenedithiolato ligands, including clusters, are known. The only reported heterometallic complexes that are assumed to contain bridging 1,1-ethylenedithiolato ligands are a few of the general formula M[Ag 2 {S 2 CC(CN)CO 2 Et} 2 ] (M = Co, Ni, Cu, Cd, Hg, Pd) and some trinuclear 1,1-dicyano-2,2-ethylenedithiolato ( i- mnt) complexes [{Ni(mnt) 2 }{ML n } 2 ] [M = Ag, L n = (PR 3 ) 2 , R = Ph, C 7 H 7 ; M = Cu, L n = (PPh 3 ) 2 , (PPh 3 ) 3 (C 3 H 6 O), (PPh 3 )(C 5 H 5 N)]. , Their proposed structures are based on a variety of techniques, but only the crystal structure of [{Ni(mnt) 2 }{Ag(PPh 3 ) 2 } 2 ] has been reported. , Although a few dithiolene complexes of the type [{M(PPh 3 ) 2 } n {S 2 CCCHC(O)R}] [M = Pd, Pt; n = 1, R = {(η 5 -C 5 H 4 ) 2 Fe(η 5 -C 5 H 5 )}; n = 2, R = {(η 5 -C 5 H 4 ) 2 Fe}] have been described, they are mononuclear or homodinuclear derivatives of ferrocenyl-substituted dithiolene ligands.…”
