Abstract
Herein
we report the first non-iron polymer obtained from an <i>ansa</i> 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 <i>ansa</i> half-sandwich complex
of this element
