摘要:
The cationic nickel, copper and zinc complexes of tris-(2-hydroxybenzyl)-aminoethylamine (H6TrenSal) have been deprotonated using potassium hydroxide. The nickel complex can be sequentially deprotonated to form a series of compounds namely, [(H6TrenSal)Ni](+), [(H6TrenSal)Ni] and "[(H6TrenSal)Ni]K". The latter is isolated as a mixture of species namely [{(H6TrenSal)Ni}K(EtOH)](2), [{(H6TrenSal)Ni}K(EtOH)(2)-mu-OH(2)](2) and [{(H6TrenSal)Ni)K(EtOH)(2)-mu-EtOH](2), which co-crystallise in a "roughly 50:27.5:22.5 ratio. In contrast the deprotonation of [(H6TrenSal)M](+) (M = Cu, Zn) results in the formation of tetrameric complexes [({(H6TrenSal)Ni}K(OH(2))(2))(4)(mu(4)-OH(2))]. (c) 2010 Elsevier B.V.
