摘要: Bu 4 N + and PPN salts of the Mn(CO) 3 (DBCat) − anion were prepared by oxidative substitution two CO ligands 5 3,5-di-tert-butyl-1,2-benzoquinone. The products was characterized crystallography UV-vis, IR, 13 C, 1 H NMR spectroscopy. complex exhibits some unusual properties: (i) it is a five-coordinate, formally 16-electron, (ii) π-acceptor (CO) π-donor (catecholate) are combined in coordination sphere, (iii) intense LMCT absorption bands observed. Crystals [Mn(CO) (DBCat)] form triclinic space group P1
