Compounds 1 and 2 (2M and 2T) have a similar packing pattern composed of mixed stacks of alternating donor-acceptor molecules. For (BET-TTF)[Au(dcdmp)2] two different crystal structures (2M and 2T) were obtained indicating polymorphism. Compounds 3 and 4 are isostructural being composed of zigzag chains of alternating donor and acceptor molecules. The salts with a 2:1 stoichiometry, (BET-TTF)2[Cu(dcdmp)2] (5), and (ET)2[Ni(dcdmp)2] (6) present the donor molecules fully oxidized and [M(dcdmp)2] (M = Ni and Cu) in a dianionic state. The salt of the dissymmetric donor \u03b1-mtdt with [Cu(dcdmp)2], \u03b1-mtdt[Cu(dcdmp)2] (7) has a crystal structure composed of segregated donor stacks that are positioned in a head-to-head fashion and alternate with the anion stacks. All charge transfer salts (1\u20137) are modest semiconductors with conductivities in the range 10\u22121\u201310\u22125 S\/cm, with the highest values obtained in \u03b1-DT-TTF salts, compounds 1 and 3.<\/jats:p>","DOI":"10.3390\/cryst8030141","type":"journal-article","created":{"date-parts":[[2018,3,20]],"date-time":"2018-03-20T15:59:39Z","timestamp":1521561579000},"page":"141","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Synthesis and Characterization of Charge Transfer Salts Based on [M(dcdmp)2] (M = Au, Cu and Ni) with TTF Type Donors"],"prefix":"10.3390","volume":"8","author":[{"given":"Rafaela","family":"Silva","sequence":"first","affiliation":[{"name":"C<sup>2<\/sup>TN, Centro de Ci\u00eancias e Tecnologias Nucleares, Instituto Superior T\u00e9cnico, Universidade de Lisboa, E.N. 10 ao km 139.7, 2695-066 Bobadela LRS, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8350-480X","authenticated-orcid":false,"given":"Isabel","family":"Santos","sequence":"additional","affiliation":[{"name":"C<sup>2<\/sup>TN, Centro de Ci\u00eancias e Tecnologias Nucleares, Instituto Superior T\u00e9cnico, Universidade de Lisboa, E.N. 10 ao km 139.7, 2695-066 Bobadela LRS, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5324-8013","authenticated-orcid":false,"given":"Sandra","family":"Raba\u00e7a","sequence":"additional","affiliation":[{"name":"C<sup>2<\/sup>TN, Centro de Ci\u00eancias e Tecnologias Nucleares, Instituto Superior T\u00e9cnico, Universidade de Lisboa, E.N. 10 ao km 139.7, 2695-066 Bobadela LRS, Portugal"}]},{"given":"Elsa","family":"Lopes","sequence":"additional","affiliation":[{"name":"C<sup>2<\/sup>TN, Centro de Ci\u00eancias e Tecnologias Nucleares, Instituto Superior T\u00e9cnico, Universidade de Lisboa, E.N. 10 ao km 139.7, 2695-066 Bobadela LRS, Portugal"}]},{"given":"Vasco","family":"Gama","sequence":"additional","affiliation":[{"name":"C<sup>2<\/sup>TN, Centro de Ci\u00eancias e Tecnologias Nucleares, Instituto Superior T\u00e9cnico, Universidade de Lisboa, E.N. 10 ao km 139.7, 2695-066 Bobadela LRS, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2222-5641","authenticated-orcid":false,"given":"Manuel","family":"Almeida","sequence":"additional","affiliation":[{"name":"C<sup>2<\/sup>TN, Centro de Ci\u00eancias e Tecnologias Nucleares, Instituto Superior T\u00e9cnico, Universidade de Lisboa, E.N. 10 ao km 139.7, 2695-066 Bobadela LRS, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8480-963X","authenticated-orcid":false,"given":"Dulce","family":"Belo","sequence":"additional","affiliation":[{"name":"C<sup>2<\/sup>TN, Centro de Ci\u00eancias e Tecnologias Nucleares, Instituto Superior T\u00e9cnico, Universidade de Lisboa, E.N. 10 ao km 139.7, 2695-066 Bobadela LRS, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2018,3,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"5319","DOI":"10.1021\/cr030655t","article-title":"Conducting Metal Dithiolene Complexes: Structural and Electronic Properties","volume":"104","author":"Kato","year":"2004","journal-title":"Chem.
