new RhIII complexes with N-substitutedsalicylaldimines have been prepared of the form [RhSBPy2]PF6 where SB is a tetradentate N,N′-substituted bis(salicylaldimine) or represents two molecules of a corresponding bidentate derivative. Several of these complexes have been reduced with 0.5% sodium amalgam and the products reacted with CH3I to yield the organometallic derivatives CH3RhSBPy.

characterisation of complexes of the type trans-[RhL4X2]Y (L = 3 or 4-substituted pyridine, 3,5-disubstituted pyridine, isoquinoline, pyrimidine, pyrazole, thiazole, X = Cl, Br and for L = py I; Y = univalent anion) are described. Using the same catalytic method, N-methylimidazole and ammonia give complexes of the type [RhL5X]2+(X = Cl or Br), whereas 5-chloro- and 5-nitro-N-methylimidazole give complexes
Synthesis, crystal structures and spectroscopic properties of cis- and trans-[RhCl2L2]+[L = 1,3-bis(dimethylphosphino)propane or 1,2-bis(dimethylphosphino)ethane (dmpe)]: reinvestigation of the dmpe complexes
and their structures and spectroscopic properties investigated. The previous characterization of the dmpe complexes made by other workers was found to be erroneous. A convenient method of preparation and separation of the complexes into isomers has been found. The geometrical structures of the isomers have been confirmed by 1H, 13C and 31P NMR spectroscopy and by single-crystal X-ray structure determinations
合成了两对几何异构体,顺式和反式[RhCl 2 L 2 ] + [L = 1,3-双(二甲基膦基)丙烷或1,2-双(二甲基膦基)乙烷],并对其结构和光谱进行了表征性能调查。发现其他工人先前对dmpe复合物的表征是错误的。已经发现了一种方便的制备方法以及将络合物分离成异构体的方法。异构体的几何结构已通过1 H,13 C和31 P NMR光谱法以及单晶X射线结构测定得到了证实。顺式的Rh–Cl键长络合物比相应的反式异构体长得多,并且顺式异构体中反式向Cl的Rh-P键比顺式和反式异构体中相互反式膦配体的相对短,表现出很强的反式影响的二甲基膦基基团。的1 H,13 C和31所述的复合物的P NMR光谱被认为是与结构一致发现通过单晶X射线分析中,并且化学位移(δ p)和偶合常数[ 1 Ĵ(RHP)和2个J(PP)]与结构参数(Rh–P键长和P–Rh–P角)非常吻合。还测定了配合物的电子光谱和异构化反应。

The preparations are described of the blue or purple complex compounds of formulae [ClL4Rh·O2·RhL4Cl]Y3 where L = pyridine or γ-picoline and Y = an anion, and [(H2O)L4Rh·O2·RhL4(H2O)]Y5. The presence of the superoxide bridge is demonstrated by magnetic, spectroscopic, and analytical data. Acid-base equilibria for the aquo-complexes are mentioned. An account is given of the reduction forming the peroxo-bridged
