Intramolecular activation processes of vulnerable ligand C-H bonds frequently limit the thermal stability and accessibility of late transition metal complexes with terminal metal nitrido units. In this study chloro substitution of the 2,6-ketimine N-aryl substituents (2,6-C(6)H(3)R(2), R = Cl) of the pyridine, diimine ligand is probed to increase the(More)
278 patients with ankylosing spondylitis have been studied in order to find a basis for prognosis by setting a mobility function index of the vertebral column. This index does not depend on manifestation age or on the blood sedimentation rate. It increases with progression of x-ray findings. A coincidence of impaired mobility and overweight is relatively(More)
Synostosing ankylosis of lower limb joints was investigated radiologically and clinically in approximately 2000 patients with ankylosing spondylitis. Ankylosis was found in 8 hip joints and in 4 of the joints of the foot skeleton. Most commonly the initial picture of these diseases is that of an arthritis (sometimes specifically misinterpreted as such)(More)
The syntheses and X-ray crystal structures of dinuclear μ-azido and μ-nitrido bridged iridium complexes bearing the pyridine, diimine ligand (PDI) are reported. Their electronic structures and formal oxidation states of the metal centers are analyzed by theoretical and experimental methods, revealing the non-innocence of the PDI and nitrido ligands.
[Ni(P(R)(2)N(R')(2))(2)(CH(3)CN)](2+) complexes with R = Ph, R' = 4-MeOPh or R = Cy, R' = Ph , and a mixed-ligand [Ni(P(R)(2)N(R')(2))(P(R''(2))N(R'(2)))(CH(3)CN)](2+) with R = Cy, R' = Ph, R'' = Ph, have been synthesized and characterized by single-crystal X-ray crystallography. These and previously reported complexes are shown to be electrocatalysts for(More)
The clinical relevance of foetal macrosomia (i.e. birth weight greater than or equal to 4000 gms) was investigated retrospectively using the 1987 figures of the "Bayerische Perinatalerhebung". 8591 (total n = 101931; 8.4%) newborns met the criterion for macrosomia and were compared with two groups of normosomic newborns (birth weight 2500-2999 gms and(More)
Obstetrical management and fetal outcome were individually analysed annually from 1987 to 1990, using computerised equipment. The individual results were discussed anonymously with all colleagues, but every colleague knew his own results. Clinical methods and obstetrical management had not been changed during the investigation period. The number of(More)
