Abstract
The preparation and interaction of the new polyaza[n]naphthalenophanes 2,5, 8,11-tetraaza[12](1,4)naphthalenophane (L1) and 2,6,9,13-tetraaza[14](1,4)n aphthalenophane (L2) with hydrogen ions and Cu2+ is described. The crystal structure of the new tetranuclear copper(II) complex [Cu-4(L1)(2)(OH)(4)Cl- 2(H2O)(2)](2)(H3O2)(ClO4)(2)Cl . 2H(2)O (L1 = 2,5,8,11-tetraaza[12](1,4)nap hthalenophane) is presented and discussed. A variety of intra- and intermol ecular forces contribute to the particular organisation of the crystal. The solution studies indicate the formation of similar tetranuclear species fo r L1 while for L2 just mononuclear 1:1 species are detected. (C) 2000 Elsev ier Science S.A. All rights reserved.
