Silicon complexes with tantalum

A shift toward utilizing physicochemical processes, newer materials, and techniques is inevitable [23]. Processes such as wafer bonding [24], stereolithography [25], and self-assembly [2 can enable complex 3D structure fabrication. Smart composite microstructures [27] of carbon, silicon, polymer, etc., can provide for robust structures with flexible joints. For tools, metals such as stainless steel, platinum-tantalum, and nickel-titanium or natural materials such as gelatin and collagen can be used. 

Compounds which accommodate agostic interactions of Si-H moieties with transition metals may also be considered as a special type of higher-coordinated silicon compounds. A few reviews on this matter are also available [36]. These include a recent general overview [37] and further publications on selected sub-topics such as platinum compounds [38] or niobium and tantalum complexes [39]. Complexes of this type are also discussed in comparison to C-H and H-H interactions with lanthanides [40].
