Co-crystal of [CuCl4]2− and L1 and its inclusion compounds with three different guests (L1 = N,N,N′,N′-tetra-p-methoxybenzyl-ethylenediamine)

Abstract

In this paper, we have built up the organic-inorganic hybrid co-crystal (1) by using the derivative of ethylenediammonium cations (N,N,N′,N′-tetra-p-methoxybenzyl-ethylenediamine, L1) and [CuCl₄]²⁻ anions. The reaction was carried out by mixing MeOH solution of CuCl₂·2H₂O and HCl/MeOH solution of L1 at room temperature. Two types of inclusion compounds can be formed when using different guest molecules. When guest molecules, such as anthracene or phenanthrene, were included, it resulted in the formation of interlayered structures: anthracene ⊂ [H₂L1]²⁺·[CuCl₄]²⁻ (2) and phenanthrene ⊂ [H₂L1]²⁺·[CuCl₄]²⁻ (3). When β-naphthyl phenol were included, it led to the formation of pillared-layered complexes of [1-chloride-β-naphthyl phenol]_1.0·[β-naphthyl phenol]_0.5·[methanol]_1.0 ⊂ 2[H₂L1]²⁺·2Cl⁻·[CuCl₄]²⁻ (4).
