To date, a substantial number of transition-metal [sigma] complexes containing [eta][sup 2]-silane ligands, [eta][sup 2]-H[sub 2] ligands, or agostic C-H bonds have been synthesized and structurally characterized. However, no systems are known in which Si-H, H-H and agostic C-H bonds can be bound to the same metal fragment in an [eta][sup 2]-fashion. In this communication, we report on the first example of such a system which provides a unique opportunity to study the differences between and/or common features among the three prototypes of [sigma] complexes. 11 refs., 1 fig., 1 tab.
