“…The Pd--CI distances of 2,294(5) and 2.296(5) ,~ are comparable with those found for other complexes with a trans CI-Pd-CI configuration [45][46][47][48]. The Pd-NI bond distance of 2.16(2) A, is relatively long with respect to other Pd-NI [45][46][47] distances of analogous complexes but comparable to the analogous distance in the complex trans-PdCI2 (2-NH2-3-Mepy) (PEt3) [48].…”

AbstractThe coordination chemistry of the new bidentate nitrogen ligands 8-( 2-pyridyl)quinoline (8-PQ) and 8-(6-methyl-2-pyridyl)quinotine) (Me-8-PQ) towards palladium and platinum has been studied. Several (NnN)Pd(R)C! and (NnN)Pd(alkene) complexes have been synthesised. The complex (8-PQ)Pd(Me)CI has been characterised by a single crystal X-ray determination (crystal dat;:: triclinic space group P / with a=8.513(5), b =9.338(4), c= 10.219(2) ,~, a= 108.11(2),/3=89.g2(3), 3, = 116.81 (4) °, V=680.I (6) .~3 R=0.033, Z--2). A fast CO insertion occurs into the palladium-carbon bond of the complexes ( NnN)Pd( Me)CI providing the ( N'~N)P,J(C(O) Me)C! c~omplexes. For ( 8-PQ)Pd(C(O)Me)CI an X-ray structure determination has been carried out (crysta! data: monoclinic space group P2Jc with a=9.084(4), b= 10.179(3), c= io.400(3) ~,,/3--95.59(2) °, V= 1509.2(9) A 3. R=0.043, Z=4). Unexpecied in both molecular structures is the large dihedral angle between the plane of the bidentate nitrogen ligand and the coordination plane of the palladium. Both bidentate coordinating ligands 8-PQ and Me-8-PQ show a relatively large bite angle. A monodentate coordination mode has been observed for the complexes (N'~N)M( PEh)CI2 (M = Pd, Pt), as the pyridyl group of the iigand is coordinated to the metal while the quinoline group i...

In this article a survey is given of novel results in the field of the chemistry of a-diimine complexes of some metal atoms of the main group, transition metal and post transition metal area. It is shown that a-diimines of the type RN=C(R')(R")C=NR (= R-DAB) and 2C&NC(R')=NR (= R-Pyca) are very versatile with regards to both their coordination chemistry and chemical reactivity when coordinated to a metal or metal cluster. The type of reaction occurring depends critically on the type of metal(s), the other ligands present on the metal(s), the type of coordination of the a-diimines, and particularly on the steric and electronic properties of R,R' and R" situated on the R-DAB and R-Pyca ligands.

“…Im Falle der sterisch weniger abgeschirmten Ru(I)-Komplexe aus 3 a, 5 und 6 wird damit eine Dimerisierung zu 4 ,7 und 8 ermöglicht, nicht dagegen für 3b. Im nachfol genden Schema, welches die Cyclovoltammogramme der Ruthenium-Organyle weitgehend zu erklären vermag, sind die entsprechenden Reaktionsfolgen zusammengefaßt: atomen ist mit 1,406(9) Ä erheblich kürzer als im freien Liganden [5,17] und kürzer als in seinem Mo(CO)4-Komplex [18]. Dieser Bindungsabstand zeigt eine erhebliche Metall-DAD-7r*-Rückbindung an.…”
