Structural characterization of a novel self-assembly heterohexanuclear complex: [Ni2Ag4(μ-dppm)4(pymt)6](SbF6)2 · 2DMF · H2O

Abstract

A novel heterohexanuclear complex [Ni 2 Ag 4 (l-dppm) 4 (pymt) 6 ](SbF 6 ) 2 AE 2DMF AE H 2 O (1), was synthesized by selfassembly with [Ag 2 (l-dppm) 2 (MeCN) 2 ](SbF 6 ) 2 and [Et 4 N][Ni(pymt) 3 ] (dppm = bis(diphenylphosphino)methane, pymt = pyrimidine-2-thiolate) as components and characterized by IR spectra, elemental analysis, 1 H-NMR spectrum, 31 P-NMR spectrum and Visible-Ultraviolet spectrum. Structure of the complex was determined by X-ray analysis.

Self-assembly and crystal structures of two heteronuclear complexes with [Ag2(μ-dppm)2(MeCN)2](SbF6)2 and [Bu4N]2[M(mnt)3] (M=Mo, W) as components

“…(pymt = pyrimidine-2-thiolate) as components affords a novel heterohexanuclear complex [Ni 2 Ag 4 (l-dppm) 4 (pymt) 6 ](SbF 6 ) 2 [20]. Recently, some other metal thiolates were used for such self-assembly reactions.…”

“…Self-assembly between such metal thiolates and metal diposphines such as [M 2 (l-dppm) 2 (MeCN) 2 ] 2+ , which are easy substituted, has been studied extensively in recent years [13][14][15][16][17][18][19][20]. It is an effective method for the synthesis of heteronuclear complexes.…”
