A series of dinuclear complexes has been prepared in which two MoV(TpMe,Me)(O)Cl} fragments (abbreviated as Mo; TpMe,Me = tris(3,5-dimethylpyrazol-1-yl)hydroborate) are attached to either end of a bis-p-phenolate bridging ligand [(4,4′-OC6H4)–X–(4,4′-C6H4O)]2−. The complexes are Mo2(CC) (X = CHCH), Mo2(CC)2 (X = CHCH–CHCH), Mo2(CC)3 (X = CHCH–CHCH–CHCH), Mo2(th) (X = 2,5-thiophenediyl), Mo2(th)2 (X = 2
制备了一系列双核配合物,其中有两个Mo V(Tp Me,Me)(O)Cl}片段(缩写为Mo; Tp Me,Me =三(3,5-二甲基吡唑-1-基)氢硼酸酯)分别连接到双-对-酚酸酯桥联配体[(4,4'-OC 6 H 4)–X-(4,4'-C 6 H 4 O)] 2-的任一端。络合物为Mo 2(C C)(X = CH CH),Mo 2(C C)2(X = CH CH–CH CH),Mo 2(C C)3(X = CH CH–CH CH–CH CH),Mo 2(th)(X = 2,5-噻吩二基),Mo 2(th)2(X = 2,5:2′,5′-联噻吩二基),Mo 2(th)3(X = 2,5:2',5':2″,5″-对噻吩二基),Mo 2( CC )(X = C C),Mo 2(N N)(X = ñ N),沫2(CO) [X = C(O)]和沫2(C 2 Φ c ^ 2)[X = CH CH(1
