Dichloro[N,N′-bis(2,6-diisopropylphenyl)-1,2-ethanediimine-N,N′]palladium

Abstract

The structure of the title complex, [PdCl2(C26H36N2)], represented as LPdCl2, where L denotes the substituted 1,2‐ethanedi­imine ligand, is described and compared with those of the analogous LPdClMe and L′PdMe2 complexes (L′ is the closely related substituted 2,3‐butane­di­imine ligand) previously reported by Tempel, Johnson, Huff, White & Brookhart [J. Am. Chem. Soc. (2000), 122, 6686–6700].

Synthesis and characterization of palladium(ii) complexes with a novel chelating iminocarbene ligand

“…Comparable Pd-N(imine) and trans Pd-Cl distances were reported as 2.014 and 2.279 Å, respectively, in a Pd diisopropylphenyl imine complex studied by Howie and coworkers. 25 The distance from Pd to the Cl trans to the carbene is substantially longer than the distance from Pd to the Cl trans to the imine in 4a, underscoring the considerably stronger trans influence from the carbene ligand than from the imine. 9c Herrmann and coworkers similarly concluded, on the basis of crystal structure data, that the carbene ligand is a stronger donor than the imine in a 6-ring carbene-oxazoline chelated Rh complex.…”

Sulfonate-tagged 1,4-diazabutadiene (DADS) ligands and their noble-metal complexes – synthesis, characterization and immobilization in ionic liquids

“…All main geometric characteristics are thus comparable to palladium dichloro complexes of non-sulfonated DAD ligands such as [PdCl 2 (2,6-iPr 2 -Me-DAD)] 38 and [PdCl 2 (2,6-iPr 2 -H-DAD)]. 39 As expected for acidic ammonium salts, 4a and 12d clearly show N-H ◊ ◊ ◊ O hydrogen bonding (N ◊ ◊ ◊ O = 299-334 pm). For all imidazolium-based salts, a relatively short contact between the N-methyl group and the sulfonate groups is found (C ◊ ◊ ◊ O = 310-318 pm).…”

α-Diimine Cisplatin Derivatives: Synthesis, Structure, Cyclic Voltammetry and Cytotoxicity

“…Complexes I and II crystallize in the monoclinic space groups P2 1/c and Cc , respectively; experimental and crystal data are presented in Table 1 . Compound I is isostructural to known palladium complex [ 40 ]. Both Pt(II) compounds are mononuclear, where the central platinum(II) ion coordinates two chloride anions and two nitrogen atoms of α-diimine moiety ( Figure 1 a,b) forming a square planar environment (selected bond distances and angles for I and II given in Table 2 ), which is quite typical for Pt 2+ , e.g., there is the same environment in starting [(CH 3 CN) 2 PtCl 2 ] [ 41 ] and similar platinum(II) complexes [L 2 PtCl 2 ], where L is N,N-dimesityl-1,4-diazabutadiene, N , N ’-bis(4-hydroxyphenyl)ethylenediamine [ 37 , 42 ].…”
