Synthesis, characterization and X-ray crystallography of a metallacrown ether complex containing a RuII(bpy)22+ chromophore and its Mo(CO)4 analog

Metallacrown ethers with a symmetric bis(phosphite) ligand derived from 1,2-bis-(2-hydroxyethoxy)benzene: Synthesis, characterization and hydroformylation of styrene

“…As compared to the previously reported cis-Mo (CO) 4 (P-donor ligand) 2 complexes [2,41,42], the octahedron is not significantly distorted as indicated by the small deviation of the phosphorus-molybdenum-phosphorus bond angle (89.40 (5) ) from the ideal angle of 90 . The coordination geometry of the palladium in 4 is a distorted square plane composed of two cis chlorines and two cis phosphites.…”

Luminescent ruthenium–polypyridine complexes & phosphorus ligands: anything but a simple story

“…7 Weakly coordinating anions such as triflato can also be displaced by phosphorus ligands (route j). 6…”

Synthesis, characterization, and coordination chemistry of two new tartaric acid-derived bis(phosphite) ligands

“…Calc. for C 16 (6) 1.455(9) C(1)-C (2) 1.538 (7) 1.494 (11) cis-PdCl 2 (2) (7). Following the procedure for 5, 0.075 g (0.42 mmol) of PdCl 2 and 0.22 g (0.42 mmol) of 2 gave 0.28 g (96%) of crude 7 as a pale yellow solid.…”

“…Thermal ellipsoids are drawn at the 50% probability level and hydrogens in calculated positions are omitted for clarity. R = OCH 2 CH 2 OEt (9), Dd = 30.47 ppm [15]) and for a complex with a long chain bis(phosphite) ligands (cis-Mo(CO) 4 {(2,2 0 -C 12 H 8 O 2 )PO(CH 2 CH 2 O) 4 P(2,2 0 -C 12 H 8 O 2 )} (10), Dd = 29.70 ppm) [16]. The coordination chemical shifts for the cis-PtCl 2 (1) complex (4, À57.07 ppm) and the cis-PdCl 2 L complexes (L = 1 (5), À33.32 ppm; L = 2 (7); À33.06 ppm) were compared to those of similar complexes of the monodentate (2,2 0 -C 12 H 8 O 2 )POCH 2-CH 2 OEt ligand, (cis-PtCl 2 L 2 (11), À54.10 ppm; cis-PdCl 2 L 2 (12), À30.09 ppm) [15].…”
