Synthesis of cationic molybdenum-cobalt heterometallic clusters protected against hydrolysis by macrocyclic triazacyclononane complexes

03-Jul-2018 | Sugiarto .; Tomoko Tagami; Keisuke Kawamoto; Yoshihito Hayashi, Dalton Transactions, 2018

Four kinds of cobalt-polyoxomolybdenum clusters were synthesized by a combination of polyoxomolybdates and a Co-tacn (tacn = 1,4,7-triazacyclononane) complex. The heterometallic polynuclear clusters were obtained by the reaction of Na2MoO4 and [Co(tacn)(H2O)3](CF3SO3)3∙H2O in aqueous solution. ...

Theoretical Studies on the Oxidation States and Electronic Structures of Actinide-Borides: AnB12 (An = Th -Cm) Clusters

03-Jul-2018 | Shuxian Hu; Mingyang Chen; Bingyun Ao, Physical Chemistry Chemical Physics, 2018

As B12 cluster exhibits significant structural stability due to double aromaticity, metal doped-B12 clusters often prefers a half sandwich structure. Here we report a systematic theoretical study on the geometric and electronic structures, and chemical bonding of the half sandwich AnB12 (An = Th ...

Ab initio study of medium sized boron-doped silicon clusters SinBm, n=11–13, m=1–3

26-Jun-2018 | Emmanuel Koukaras, Physical Chemistry Chemical Physics, 2018

The ground state and energetically low structures of neutral SinBm clusters, of medium sizes with n=11–13, m=1–3, are presented. Structures of the nanoclusters are predicted using density functional theory (DFT) and employing the HSE06 range-separated hybrid exchange–correlation functional. For ...
