The cover picture shows three heterobimetallic sodium‐bismuth‐oxo silanolates: [Bi 10 Na 5 O 7 (OH) 6 (OSiMe 3 ) 15 ] ( 2 ), [Bi 15 ‐Na 3 O 18 (OSiMe 3 ) 12 ] ( 3 ) and [Bi 14 Na 8 O 18 (OSiMe 3 ) 14 (thf) 4 ] ( 4 ). These novel polynuclear metal‐oxo clusters were obtained in addition to the hexanuclear oxygen‐centred complex [Bi 2 Na 4 O(OSiMe 3 ) 8 ] ( 1 ), which represents a well‐known structural motif found in several heterometallic group 15/group 1 compounds. As result of the similar ionic radii of sodium and bismuth and the flexible coordination chemistry of these main group metals, the formation of a large variety of heterobimetallic molecular structures is conceivable. Structural relationships between the metal‐oxo silanolates are described and a comparison with other polynuclear bismuth‐oxo compounds is given in order to identify basic building blocks. The approach is envisaged to develop rational design strategies towards molecular bismuth‐containing precursors for heterometallic materials. Details are discussed in the article by M. Mehring et al. on p. 4891 ff.
