The synthesis of the facultative quadridentate ligand. 1,3-bis(3′-dimethylarsinopropylthio)propane (L), is described. Twenty complexes of CoII, NiII, PdII, and PtII have been prepared and the variety of the resulting stereochemistries demonstrates the utility of open-chainligands in allowing such factors as electronic properties of the metal ions, nature of the solvent, and counter ions to also dictate
兼性四元配体的合成。描述了1,3-双(3'-二甲基亚氨基丙基硫基)丙烷(L)。已经制备了二十种Co II,Ni II,Pd II和Pt II配合物,各种立体化学方法证明了开链配体在允许诸如金属离子的电子性质,溶剂的性质,和抗衡离子也决定了结构。晒黑-伪八面体[NIX 2 L]络合物对于X =氯,溴,或NCS获得,但对于X = I反磁性[NiIL]我的结果。[NiCl 2 L]配合物容易转变为平面[NiL] X 2,通过三角-双锥体中间体。在溶解[MXL] +(M = Pd或Pt)配合物时观察到一种不同寻常的反螯合双齿行为,该配合物的MAs 2 S 2 X供体在固态和在硝基甲烷中。在卤代有机溶剂中形成供体组MAs 2 X 2的平面[MX 2 L]物质。
