The cover picture shows the branched triphosphanyltetrasilane PhSi(SiMe 2 PH 2 ) 3 , which was obtained in a three‐stage synthesis and characterised by multi‐nuclear NMR spectroscopy, mass spectrometry and IR spectroscopy. By deprotonation, this birdcage‐like ligand catches the alkaline earth metals Ca, Sr and Ba in three different ways yielding new phosphorus bridged polynuclear complexes. In the case of calcium, two trigonal bipyramidal cages are observed, the strontium compound shows two semi cubes; and in case of barium, a three times bridged trigonal prism can be observed. More details concerning the synthesis and structures of these compounds are discussed in the article by C. von Hänisch et al. on pp. 788 ff.
