Synthesis and structural characterisation of Group 11 metal complexes with a phosphinoferrocene oxazoline

Abstract

Interactions of phosphinoferrocene oxazolines with Group 11 metals were elucidated. The differences dictated by the metal ions are discussed.

Synthesis and Photophysical Properties of Emissive Silver(I) Halogenido Coordination Polymers Composed of {Ag2X2} Units Bridged by Pyrazine, Methylpyrazine, and Aminopyrazine

“…The structures of AgX-L and CuBr-L prepared in this study are typical for complexes with the formula [M 2 X 2 (PPh 3 ) 2 (μ-L)] n (M = Cu, Ag; X = I, Br, Cl). − ,, As shown in Tables S4 and S5, the bond distances around the silver atom in the present complexes are in the range of related compounds having Ag 2 X 2 P 2 N 2 geometry (Table S6). ,,− As shown in Tables S5 and S7, whereas the difference between Ag–P av and Cu– P av (0.20 Å) is comparable to the differences between Ag–Br av (2.73 Å) and Cu–Br av (2.54 Å), the difference between Ag–N av and Cu–N av is 0.30 Å, showing that imino ligand L is less favorable for the monovalent silver ion than the phosphine ligand, which can explain the requirement of an excess amount of L in the synthesis of AgX-L . Although various ligands are known to afford [Cu 2 X 2 (PPh 3 ) 2 (L) n ] ( n = 1, 2), − only 4,4′-bipyridine (bpy), 2-aminopyrimidine, , 2-aminopyridine, and pyridine , have been reported to afford [Ag 2 X 2 (PPh 3 ) 2 (L) n ].…”

Dinuclear silver(I) and gold(I) complexes with chiral oxazoline‐NHC ligands

“…[21] In 2018, Štěpnička et al used a racemic phosphanoferrocene ligand bearing an achiral oxazoline arm in combination with group 11 metal complexes. [22] With gold, no coordination of the oxazoline ring was achieved. Metalation of the ligand with tetrahydrothiophene gold(I) complexes Au(tht)Cl or Au(tht)(ClO 4 ) yielded respectively the neutral phosphane gold(I) chloride complex or the cationic bis-phosphine gold(I) perchlorate complex.…”
