Аннотация

The reaction of Re3Br9 with P(CH2OH)3 (THP) in methanol under inert atmosphere gives a new cluster complex, [Re3(µ2‑Br)3Br3(µ3-P,O,O-P(CH2OH)(CH2O)2)2H] ∙ 0.8H2O · 1.6MeOH (I). With access of air, the reaction produces a different product, [{Re3(µ2-Br)3Br2(OCH2)2PCH2-OP(CH2OH)2}2-{(P(CH2OH)(CH2O)2)}2] (II), in which two triangular clusters are linked by deprotonated THP molecules as bridging ligands. In addition, each cluster is coordinated in a tetradentate fashion by the phosphine-phosphinite ligand, resulting from the oxidative condensation of two THP molecules (CIF files CCDC 1829565 (I) and 1829566 (II)).
