文摘

Herein we report the first non-iron polymer obtained from an ansa half-sandwich complex. This polymeric organometallic material was obtained from a new disilanediyl-bridged ruthenium complex upon thermally induced ring-opening polymerization (ROP). Additionally, a corresponding distannanediyl-bridged osmium species is reported, the first example of an ansa half-sandwich complex of this element.
