“…As in [Ag(PPh 3 ) 4 ] + , the coordination of Ag(I) in [Ag(Phang) 4 ] + is approximately tetrahedral, and the P–Ag–P bond angles lie in the range 107.5–112.2°, with an average of 109.5°. The average length of Ag–P bonds in [Ag(Phang) 4 ] + is 2.456 Å, which is substantially shorter than the Ag–P bonds in [Ag(PPh 3 ) 4 ] + (2.60–2.68 Å). − The difference can be attributed to the smaller cone angle of phosphangulene, which reduces repulsive intracomplex ligand–ligand interactions created when the ligand approaches the metal more closely.…”

“…The coordination of Ag(I) by phosphines has been studied for many decades, and the subject has been reviewed . Tetracoordination of Ag(I) to give [Ag(PPh 3 ) 4 ] + was first reported in 1960, and the structures of many salts have been published. − As a result, we began by targeting the preparation of salts of [Ag(Phang) 4 ] + . Single crystals of the BF 4 – salt were obtained by combining AgBF 4 with phosphangulene in CH 2 Cl 2 in a 1:4 ratio, followed by slow evaporation of solvent under N 2 in the dark.…”

Building Large Structures with Curved Aromatic Surfaces by Complexing Metals with Phosphangulene

Phosphangulene (1) is a hexacyclic triarylphosphine with a distinctive conical shape and an electron-rich aromatic surface that is geometrically and electronically complementary to fullerenes such as C60 and C70. As a result, suitable derivatives of phosphangulene can cocrystallize with fullerenes or even bind them in solution. Surprisingly, previous work has largely overlooked the potential of phosphangulene to form complexes with metals, which offers a simple way to create large molecular structures with curved aromatic surfaces. To explore this approach, we have prepared and characterized a series of complexes of phosphangulene with Ag+ and Cu+. Our results show that Phang ligands are exceptional for many reasons. In particular, they can yield metal complexes with unique coordination, and the metal centers hold the concave aromatic surfaces of multiple ligands in various divergent arrays. Moreover, the rigid conical structure of phosphangulene gives the complexes an awkward shape that cannot be packed efficiently without complementary partners. As a result, metal complexes of phosphangulene are predisposed to cocrystallize with fullerenes, thereby yielding materials in which metals and fullerenes are brought together in ordered arrangements.

“…Especially, some compounds containing silver and triphenylphosphine have been synthesized [5][6][7]. Herein, we report the title complex[Ag(PPh 3 ) 2 (CH 3 OH)BF 4 ], which was unexpectedly obtained in an attempt to prepare a silver(I) complex of 2,5-dimercapto-1,3,4-thiadiazole and PPh 3 .…”

C 37 H 34 AgBF 4 OP 2 , monoclinic, P2 1 /n (no. 14), a = 13.748(1) Å, b = 12.757(1) Å, c = 19.716(2) Å, b = 92.657(1)°,Source of material 2,5-dimercapto-1,3,4-thiadiazole (0.1 mmol, 0.015 g) and triphenylphosphine (PPh 3 , 0.4 mmol, 0.105 g) were added into the stirring solution of AgBF 4 (0.2 mmol, 0.039 g) in a mixture of CH 2 Cl 2 (5ml) and CH 3 OH (5ml). After being stirred for 2h at room temperature, the white precipitate was filtered off. Subsequent slow evaporation of the colourless filtrate resulted in the formation of colourless crystals of the title complex [Ag(PPh 3 ) 2 (CH 3 OH)BF 4 ]. Crystals suitable for single crystal Xray diffraction were selected directly from the sample as prepared.

The asymmetric unit of the title compound, [Ag(C5H8N4)3](CF3O3S)·C5H8N4, contains two cations, two anions and two uncoordinated 3-amino-5,6-dimethyl-1,2,4-triazine (admt) ligands. It was prepared from the reaction of silver trifluoromethanesulfonate and admt in a 2:3 molar ratio. Both silver(I) ions are bonded to three admt molecules via their 2-position triazine N atoms in almost regular trigonal–planar geometries. Three intramolecular N—H⋯N hydrogen bonds between adjacent admt molecules in each cation help to maintain their overall near planarities (r.m.s. deviations for the 28 non-H atoms = 0.139 and 0.153 Å). In the crystal, numerous N—H⋯N, N—H⋯O, C—H⋯O, C—H⋯N and C—H⋯F hydrogen-bonding interactions link the components into a three-dimensional network.

Tetrakis(triphenylphosphane-κP)silver(I) trifluoromethanesulfonate dichloromethane monosolvate

Abstract: In the title compound, [Ag(C18H15P)4]CF3O3S·CH2Cl2, the Ag atom is coordinated by four P atoms from four PPh3 ligands. The P—Ag—P angles are in the range 108.02 (6)–110.15 (6)°, which confirms the distorted tetrahedral environment around the Ag atom.
