To date, this has been achieved through the use of multipodal compounds (i.e., containing more than two anchoring groups), resulting in the formation of tri/tetrapodal compounds. While such compounds have greatly improved orientation control, this comes at the cost of lower surface coverage. In this study, we examine an alternative approach for generating multimodal compounds by binding multiple independent molecular wires together through metal coordination to form a molecular bundle. This was achieved by coordinating iron(II) and cobalt(II) to 5,5′-bis(methylthio)-2,2′-bipyridine (L1) and (methylenebis(4,1-phenylene))bis(1-(5-(methylthio)pyridin-2-yl)methanimine) (L2) to give two monometallic complexes, Fe-1 and Co-1, and two bimetallic helicates, Fe-2 and Co-2. Using XPS, all of the complexes were shown to bind to a gold surface in a fac fashion through three thiomethyl groups. Using single-molecule conductance and DFT calculations, each of the ligands was shown to conduct as an independent wire with no impact from the rest of the complex. These results suggest that this is a useful approach for controlling the geometry of junction formation without altering the conductance behavior of the individual molecular wires. 000129977 536__ $$9info:eu-repo/grantAgreement/ES/DGA/E31-20R$$9info:eu-repo/grantAgreement/ES/MICINN/PID2019-105881RB-I00$$9info:eu-repo/grantAgreement/EUR/MICINN/TED2021-131318B-I00 000129977 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000129977 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000129977 700__ $$aPlanje, Inco J. 000129977 700__ $$aAlmughathawi, Renad 000129977 700__ $$aNaghibi, Saman 000129977 700__ $$aVezzoli, Andrea 000129977 700__ $$aMilan, David C. 000129977 700__ $$aLambert, Colin 000129977 700__ $$0(orcid)0000-0001-9193-3874$$aMartin, Santiago$$uUniversidad de Zaragoza 000129977 700__ $$0(orcid)0000-0002-4729-9578$$aCea, Pilar$$uUniversidad de Zaragoza 000129977 700__ $$aNichols, Richard J. 000129977 700__ $$aHiggins, Simon J. 000129977 700__ $$aYufit, Dmitry S. 000129977 700__ $$aSangtarash, Sara 000129977 700__ $$aDavidson, Ross J. 000129977 700__ $$aBeeby, Andrew 000129977 7102_ $$12012$$2755$$aUniversidad de Zaragoza$$bDpto.
