Treatment of meso-malonylidene-(m-benzi)porphyrin and meso-malonylidene-(m-benzi)pentaphyrin with Pd(ii), Au(iii), Ni(ii) and Ag(i) afforded the corresponding metal complexes. The synthesized metal complexes were characterized by spectroscopy including single crystal X-ray, NMR and mass spectrometry. Most metal complexes were stable in solution. The metal complexes showed strong absorption in t...
The in situ combination of M(II) cations (Co, Ni, Cu or Zn) with 2,4,6-pyridinetricarboxylic acid as a ligand, a bisamidinium dication as a H-bond donor tecton and NaOH leads to the formation of anionic metal complexes ML2(2-) and their interconnection into isomorphous 3D H-bonded networks displaying different colours which were used as preformed seed crystals for the formation of crystals of c...
The fac-Ir(ppy)₃ complex, where ppy denotes 2-phenylpyridine, is one of the well-known luminescent metal complexes having a high quantum yield. However, there have been no specific molecular design guidelines for color tuning. For example, it is still unclear how its optical properties are changed when changing substitution groups of ligands. Therefore, in this study, differences in the electro...

The first stable dianionic Janus-type bis(maloNHC) was isolated and characterized. Details on the chemistry of this biscarbene with respect to its ability to support catalytically relevant metal complexes are provided. The molecular structures of two dinuclear gold and silver complexes were determined by X-ray crystallography.
Many transition metal complexes accomplish or catalyze the oxidation of C H, O H, and other -bonds. Under aerobic conditions, metal complexes typically modulate an autoxidation radical chain. In anaerobic reactions, a metal complex can be the reactive species that attacks t c a r h s d ©
The paper makes two related contributions. First, and in contrast with the rich body of literature on collusion with (mainly perfect) substitutes, it derives general results on the sustainability of tacit coordination for a class of nested demand functions that allows for the full range between perfect substitutes and perfect complements. Second, it studies the desirability of joint marketing a...
This report sets out the results of an investigation into the distributed implementation of tuple spaces, hence Linda. There are numerous such schemes for implementing distributed tuple spaces, and a selection of these implementations are examined. It is observed that all the implementations have a great deal of similarities. These similarities form the basis for a generalised tuple space imple...
