The solid-state structures of 5, 7, 9, 12, 13, 15, and 16 ([TiCl2(\u03ba2O,O\u2032-PhC(O)CHC(O)Ph)2]) show that 7 and 9 exist in their \u03b2-diketo form. Compound 13 crystallizes as a tetramer based on a hydrogen bond pattern, including one central water molecule. The electrochemical behavior of 5\u20137 and 9\u201316 was studied by cyclic and square-wave voltammetry, showing that the ferrocenyls can separately be oxidized reversibly between \u221250 and 750 mV (5\u20137, 9, 12\u201315: two Fc-related events; 10, 11: six events, being partially superimposed). For complex 10, Ti-centered reversible redox processes appear at \u2212985 (TiII\/TiIII) and \u2212520 mV (TiIII\/TiIV). Spectro-electrochemical UV-Vis\/NIR measurements were carried out on 5, 6, and 12, whereby only 12 showed an IVCT (intervalence charge-transfer) band of considerable strength (\u03bdmax = 6250 cm\u22121, \u0394\u03bd\u00bd = 4725 cm\u22121, \u03b5max = 240 L\u00b7mol\u22121\u00b7cm\u22121), due to the rigid C3O2B cycle, enlarging the coupling strength between the Fc groups.<\/jats:p>","DOI":"10.3390\/molecules25194476","type":"journal-article","created":{"date-parts":[[2020,9,29]],"date-time":"2020-09-29T08:43:27Z","timestamp":1601369007000},"page":"4476","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Synthesis, Characterization, and Electrochemistry of Diferrocenyl \u03b2-Diketones, -Diketonates, and Pyrazoles"],"prefix":"10.3390","volume":"25","author":[{"given":"Steve W.","family":"Lehrich","sequence":"first","affiliation":[{"name":"Anorganische Chemie, Institut f\u00fcr Chemie, Fakult\u00e4t f\u00fcr Naturwissenschaften, Technische Universit\u00e4t Chemnitz, D-09107 Chemnitz, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julia","family":"Mahrholdt","sequence":"additional","affiliation":[{"name":"Anorganische Chemie, Institut f\u00fcr Chemie, Fakult\u00e4t f\u00fcr Naturwissenschaften, Technische Universit\u00e4t Chemnitz, D-09107 Chemnitz, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5453-4137","authenticated-orcid":false,"given":"Marcus","family":"Korb","sequence":"additional","affiliation":[{"name":"School of Molecular Sciences, The University of Western Australia, 35 Stirling Highway, Crawley, Perth, WA 6009, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexander","family":"Hildebrandt","sequence":"additional","affiliation":[{"name":"Anorganische Chemie, Institut f\u00fcr Chemie, Fakult\u00e4t f\u00fcr Naturwissenschaften, Technische Universit\u00e4t Chemnitz, D-09107 Chemnitz, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jannie C.","family":"Swarts","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of the Free State, P.O.
