Syntheses and crystal structures of novel heterobimetallic tantalum coin metal chalcogenido clusters
In the presence of phosphine the thiotantalats (Et4N)4[Ta6S17] ¡¤ 3MeCN reacts with copper to give a number of new heterobimetallic tantalum copper chalcogenide dusters. These clusters show metal chalcogenide units some of which here already known from the chemistry of vanadium and niobium. New Ta – M-chalcogenide dusters could also be synthesised by reaction of TaCl5 and silylated chalcogen reagents with copper or silver salts in presence of phosphine. Such examples are: [Ta2Cu2S4Cl2(PMe3) 6] ¡¤ DMF (1), (Et4N)[Ta3Cu5S8Cl5 (PMe3)6] ¡¤ 2MeCN (2), (Et4N)[Ta9Cu10S24Cl8 (PMe3)14] ¡¤ 2MeCN (3), [Ta4Cu12Cl8S12(PMe3) 12] (4), (Et4N)[Ta2Cu6S6Cl5 (PPh3)6] ¡¤ 5MeCN (5), (Et4N)[Ta2Cu6S6Cl5 (PPh2Me)6] ¡¤ 2MeCN (6), (Et4N)[Ta2Cu6S6Cl5 (ptBu2Cl)6] ¡¤ MeCN (7) [Ta2Cu2S4Br4(PPh3) 2(MeCN)2] ¡¤ MeCN (8), [Cu(PMe3)4]2[Ta2Cu6S 6(SCN)6(PMe3)6] ¡¤ 4MeCN (9), [TaCu5S4Cl2(dppm)4] ¡¤ DMF (10), [Ta2Cu2Se4(SCN)2(PMe 3)6] (11), [Cu(PMe3)4]2[Ta2Cu6Se 6(SCN)6(PMe3)6] ¡¤ 4MeCN (12), [TaCu4Se4(PnPr3)6] [TaCl6] (13), [Ta2Ag2 Se4Cl2(PMe3)6] ¡¤ MeCN (14), ?[TaAg3Se4(PMe3)3] (15). The structures of these compounds were obtained by X-ray single crystal structure analysis.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.COA of Formula: CCuNS, you can also check out more blogs about1111-67-7
