Synthesis, spectroscopy and structures of palladium(II) and platinum(II) complexes containing mercapto-o-carborane

1-Selenolato-2-phenyl-o-carborane complexes of palladium(II) and platinum(II): Synthesis, spectroscopy and structures

“…6) showed particles are spherical in shape with an average diameter of 100 nm. Recently extrusion of carborane in metal complexes has been reported [13,27].…”

“…Several of these chalcogenides show semiconducting properties and find numerous applications in electronic industry and catalysis [10]. Recently we have described the synthesis of mononuclear palladium and platinum complexes derived from 2-mercapto carboranes [13]. The three dimensional steric demand of carborane has led to subtle differences in the reactivity of these complexes when compared with those containing simple thiolate ligands.…”

Reactions of benzyldiphenylphosphine with Pd(II) sources on silica gel

“…In general, preparation and use of cyclopalladated [21,22] and Pd(II) coordination complexes of phosphines have been subjects of considerable interest for a few decades. The main application of these complexes is in catalysis [23], although they have been also used as precursors for synthesis of valuable organic compounds [24] and other Pd complexes [25,26]. Therefore, the importance of phosphinederived Pd(II) complexes as well as a growing demand for green approaches in synthesis have warranted our study of reactions of PBnPh 2 with Pd(II) sources on SiO 2 .…”

Syntheses and Structures of Group 10 Metal POCOP Pincer Complexes Bearing A Mercapto‐o–carborane Auxiliary Ligand

“…[2b,g,i,k,m, ° ,p,q,7] In the structure of complex 1 , the Ni‐C ipso bond length (1.896(3) Å) is comparable with those of the corresponding POCOP−Ni phenylthiolate/benzylthiolate (SPh/SCH 2 Ph) complexes (1.880(2)‐1.910(3) Å); however, the Ni−S bond length (2.2438(11) Å) is longer than those of the most POCOP−Ni‐SPh/SCH 2 Ph complexes (2.1734(6)‐2.2556(9) Å) ,. For complex 2 , the Pd‐C ipso bond length (1.995(3) Å) is similar to those of the correlated POCOP−Pd‐SPh/SCH 2 Ph complexes (2.000(4)‐2.015(2) Å); nevertheless, the Pd−S bond length (2.3974(10) Å) is slightly longer than those of the POCOP−Pd‐SPh/SCH 2 Ph complexes (2.3635(8)‐2.3745(12) Å) and noticeably longer than those of several Pd(II) complexes with square‐planar configuration bearing 1‐mercapto‐2‐phenyl‐ o ‐carborane ligands (2.302(1)‐2.3595(4) Å) . Although the Pt‐C ipso bond length in complex 3 (1.998(4) Å) is not significantly different from those of the related pincer platinum complexes (1.96(4)‐2.063(4) Å), the Pt−S bond length (2.3906(12) Å) is much longer than a terpyridine based NNN type pincer platinum complex with methanethiolato‐ m ‐carborane auxiliary ligands (2.2967(16) Å) .…”
