It has been found that the delta --> delta* band in the electronic absorption spectra of a series of bis(arylimino)isoindoline dimolybdenum complexes, Mo2(BAII)(OAc)3, follows three trends. First, as the energy of the band decreases across the series its intensity increases. Second, as electron-releasing groups are added to the aryl portion of the ligand the energy of the band increases, while addition of electron-releasing groups decreases its energy. Third, as the parent aryl group becomes a better pi-acceptor the band's energy decreases. These three trends are taken to indicate that the energy of the delta --> delta* band in this series of compounds is determined by mixing of a ligand-to-metal charge-transfer transition with the original delta --> delta* transition.

Two new palladium(II) complexes of stericallyhindered 1,3-bis-(4-methyl-2-thiazolylimino)isoindoline ligands [(4-MeBTI)PdX] with X = OAc (4) and X = Cl (5) have been prepared from the free base H(4-MeBTI) (3) and Pd(OAc)2 or PdCl2, respectively, in good yields. Both species reside as distinct mononuclear entities in the solid state, the latter as a chloroform solvate. The acetato derivative 4 is slowly
空间位阻 1,3-双-(4-甲基-2-噻唑亚氨基)异吲哚啉配体 [(4-MeBTI) PdX] 的两种新钯 (II) 配合物,其中 X = OAc (4) 和 X = Cl (5)分别由游离碱 H (4-MeBTI) (3) 和 Pd (OAc) 2 或 PdCl2 制备,产率良好。两种物质在固态下都作为不同的单核实体存在,后者作为氯仿溶剂化物。乙酰基衍生物4在氯仿的作用下或通过盐复分解反应被氯阴离子缓慢转化为氯代络合物5。可以得到含有这两种化合物的混合晶体,其中分子位于 5 × CHCl3 的同型排列中。
