The number of the stereogenic centers, their relative location on the molecule, the nature of the counter-ion and the electrocrystallization conditions play a paramount role in the crystal structures and conducting properties of the resulting materials. Here, we report the preparation and detailed structural characterization of the following series of radical cation salts: (i) mixed valence (1)2AsF6 as racemic, and (S) and (R) enantiomers; (ii) [(S)-1]AsF6\u00b7C4H8O and [(R)-1]AsF6\u00b7C4H8O where a strong dimerization of the donors is observed; (iii) (1)I3 and (2)I3 as racemic and enantiopure forms and (iv) [(meso)-2]PF6 and [(meso)-2]XO4 (X = Cl, Re), based on the new donor (meso)-2. In the latter, the two methyl substituents necessarily adopt axial and equatorial conformations, thus leading to a completely different packing of the donors when compared to the chiral form (S,S)\/(R,R) of 2 in its radical cation salts. Single crystal resistivity measurements, complemented by thermoelectric power measurements in the case of (1)2AsF6, suggest quasi-metallic conductivity for the latter in the high temperature regime, with \u03c3RT \u2248 1\u201310 S cm\u20131, while semiconducting behavior is observed for the (meso)-2 based salts.<\/jats:p>","DOI":"10.3390\/magnetochemistry7060087","type":"journal-article","created":{"date-parts":[[2021,6,20]],"date-time":"2021-06-20T22:00:02Z","timestamp":1624226402000},"page":"87","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Chiral Radical Cation Salts of Me-EDT-TTF and DM-EDT-TTF with Octahedral, Linear and Tetrahedral Monoanions"],"prefix":"10.3390","volume":"7","author":[{"given":"Nabil","family":"Mroweh","sequence":"first","affiliation":[{"name":"Univ Angers, CNRS, MOLTECH-Anjou, SFR MATRIX, F-49000 Angers, France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7966-8107","authenticated-orcid":false,"given":"Alexandra","family":"Bogdan","sequence":"additional","affiliation":[{"name":"Univ Angers, CNRS, MOLTECH-Anjou, SFR MATRIX, F-49000 Angers, France"}]},{"given":"Flavia","family":"Pop","sequence":"additional","affiliation":[{"name":"Univ Angers, CNRS, MOLTECH-Anjou, SFR MATRIX, F-49000 Angers, France"}]},{"given":"Pascale","family":"Auban-Senzier","sequence":"additional","affiliation":[{"name":"Laboratoire de Physique des Solides, Universit\u00e9 Paris-Saclay CNRS UMR 8502, B\u00e2t. 510, 91405 Orsay, France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2598-7940","authenticated-orcid":false,"given":"Nicolas","family":"Vanthuyne","sequence":"additional","affiliation":[{"name":"Aix Marseille Universit\u00e9, CNRS, Centrale Marseille, iSm2, 13013 Marseille, France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1855-7758","authenticated-orcid":false,"given":"Elsa B.","family":"Lopes","sequence":"additional","affiliation":[{"name":"Centro de Ciencias e Tecnologias Nucleares (C2TN) and Departmento de Engenharia e Ciencias Nucleares(DECN), Instituto Superior T\u00e9cnico (IST), Universidade de Lisboa, E.N. 10, 2695-066 Bobadela LRS, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2222-5641","authenticated-orcid":false,"given":"Manuel","family":"Almeida","sequence":"additional","affiliation":[{"name":"Centro de Ciencias e Tecnologias Nucleares (C2TN) and Departmento de Engenharia e Ciencias Nucleares(DECN), Instituto Superior T\u00e9cnico (IST), Universidade de Lisboa, E.N. 10, 2695-066 Bobadela LRS, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9970-4494","authenticated-orcid":false,"given":"Narcis","family":"Avarvari","sequence":"additional","affiliation":[{"name":"Univ Angers, CNRS, MOLTECH-Anjou, SFR MATRIX, F-49000 Angers, France"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"4061","DOI":"10.1039\/b820598a","article-title":"Strategies Towards Chiral Molecular Conductors","volume":"19","author":"Avarvari","year":"2009","journal-title":"J.
