Quadruply bonded metal complexes, where M = Mo, W, that incorporate thienylethynyl and thienylvinyl carboxylates are being synthesized. Varying the bond order of the C$\mathrm{<mrow\; data-mjx-texclass="ORD">2</mrow>}$ unit between the thienyl group and the carboxylate tether provides a series of complexes in which a comparative study on the electronic delocalization in the ground and excited states can be conducted. The properties of these complexes will be predicted by DFT calculations and probed by steady-state absorbance, emission, electrochemistry, and ns- and fs-transient absorption.
