(1−) (10). Ready displacement of naphthalene in 10 by L = 1,3-butadiene, 2,2′-bipyridine, and COD occurs to give good yields of the respective [Co(L)(COD)]−, all of which have been structurallycharacterized. Both ligands in 10 are displaced by tert-butylisocyanide to afford [Co(CNtBu)4]− (16), the first isolable and structurallycharacterized homoleptic alkylisocyanometalate. The molecular structure

Alkali metal naphthalenide or anthracenide reacted with scandium(III) anilides [Sc(X)N(tBu)Xy}2(thf)] (X=N(tBu)Xy (1 ); X=Cl (2 ); Xy=C6H3‐3,5‐Me2) to give scandium complexes [M(thf)n ][ScN(tBu)Xy}2(RA)] (M=Li–K; n =1–6; RA=C10H82− (3‐Naph‐K ) and C14H102− (3‐Anth‐M )) containing a reduced arene ligand. Single‐crystal X‐ray diffraction revealed the scandium(III) center bonded to the naphthalene
碱金属萘化物或蒽化物与苯胺钪(III)反应[Sc(X)N( tBu )Xy} 2 (thf)](X=N( tBu )Xy( 1 );X=Cl( 2 ); Xy=C 6 H 3 ‐3,5-Me 2 ) 得到钪络合物 [M(thf) n ][ScN( t Bu)Xy} 2 (RA)] (M=Li–K; n =1 –6; RA=C 10 H 8 2− ( 3-Naph-K ) 和 C 14 H 10 2− ( 3-Anth-M )) 含有还原芳烃配体。单晶X射线衍射显示,钪(III)中心以σ 2 :π-配位模式与萘二价阴离子键合,而蒽二价阴离子以σ 2 -方式对称地连接到钪(III)中心。所有化合物均经过多核表征,包括45 Sc NMR 光谱。这些浓色芳烃配合物的量子化学计算证实钪处于+3氧化态。在紫外/可见光谱中观察到的强烈吸收是由于配体到金属的电荷转移。虽然腈与还原芳烃配体发生 C−C 偶联反应,但与一当量的

High-quality polycrystalline polyacenes (PLAs) of anthracene (AN), tetracene (TN), and pentacene (PN) doped with potassium in the 1:1 and 1:2 stoichiometries are prepared and their physical properties are systematically studied by magnetic measurements. The magnetic susceptibilities as a function of temperature for Kx(PLAs) are interpreted in the framework of a band-filling model. Clear evidence for
