Ag 2 (l-dppm) 2 (tptz)(MeCN)](SbF 6 ) 2 AE2H 2 OAE2MeCN (1), [Ag 2 (l-dppm) 2 (tptz) 2 ](SbF 6 ) 2 AE1.75H 2 O (2) and [Ag 2 (l-dppm) (tptz) 2 ](SbF 6 ) 2 AE 2MeCN (3) were synthesized by self-assembly with metal diphosphine [Ag 2 (l-dppm) 2 (MeCN) 2 ](SbF 6 ) 2 and tptz as components in different molar ratios [(dppm = bis(diphenylphosphino)methane and tptz = 2,4,6-tris (2¢-pyridyl)-1,3,5-triazine)] and characterized by IR spectra, elemental analysis, 1 H NMR spectra, 31 P NMR spectra and Visible-Ultraviolet spectra. Structures of all the complexes were determined by X-ray analysis. p ) p interactions were found in complex (3). Further studies show that all the complexes were of well luminescent properties both in solution and solid state.
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.
Two heteronuclear complexes Mo 2 Ag 4 (l-dppm) 4 (mnt) 6 Á 6MeCN (1) and WAg 2 (l-dppm) 2 (mnt) 3 Á MeCN (2) were synthesized by self-assembly with [Ag 2 (l-dppm) 2 (MeCN) 2 ](SbF 6 ) 2 and [Bu 4 N] 2 [Mmnt) 3 ] (M=Mo or W, dppm=bis(diphenylphosphino)methane, mnt 2-= cis-1,2-dicyanoethylene-1,2-dithiolate) as components and characterized by IR spectra, elemental analysis, 1 H NMR spectra, 31 P NMR spectra and u.v.-vis spectra. The crystal structures of the two complexes were determined by X-ray analysis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
