A two-dimensional layer inN,N′-bis[2-(hydroxymethyl)benzyl]ethylenediamine and a three-dimensional network inN,N′-bis[2-(hydroxymethyl)benzyl]ethylenediammonium bis(perchlorate)

Abstract

In both title compounds, C(18)H(24)N(2)O(2), (Ia), and C(18)H(26)N(2)O(2)(2+) x 2 ClO(4)(-), (II), respectively, the two aryl rings are strictly parallel, with an inversion centre lying at the mid-point of each central CH(2)-CH(2) bond. Molecules in (Ia) are linked into two-dimensional layers by N-H...O hydrogen bonds. The component ions in (II) are joined together by a combination of N/O/C-H...O hydrogen bonds and C-H...pi and anion...pi interactions, forming a three-dimensional network. A structural understanding of (Ia) and (II) may provide some useful information about how and why their metal-organic complexes display various biological activities and function in catalytic processes.
