- Abstract
- The hydrothermal reaction of fumaric acid, benzylamine and cuprous chloride yielded Cu[(rac-N-benzyl-Asp)(benzylamine)(H2O)] 1, while ethylenediamine, 1,3-diaminopropane and piperazine produced Cu[rac-N-aminoethyl-Asp] 2, Cu[rac-N-aminopropyl-Asp] 3 and Cu[rac-piperazinyl succinate](2) 4, respectively. Under mild hydrothermal conditions, Michael addition of benzylamine, ethylenediamine, 1,3-diaminopropane and piperazine to fumaric acid led to the formation of racemic mixtures of N-benzyl aspartic acid, N-aminoethyl aspartic acid, N-aminopropyl aspartic acid and piperazinyl succinic acid, respectively. The structure of 1 consists of one-dimensional polymeric chains in which copper cations are bridged by D- and L-N-benzyl aspartate anions alternatively along the chain. Additional benzylamine and water molecules bond to copper cations to complete the Cu[(rac-N-benzyl-Asp)(benzylamine)(H2O)] chain. The structures of 2 and 3 consist of one-dimensional polymeric chains in which copper cations are bridged by D- and L-N-aminoethyl and aminopropyl aspartate anions alternatively along the chains. The structure of 4 is composed of discrete Cu[rac-piperazinyl succinate](2) units that are connected by hydrogen bonds. (C) 2015 Elsevier B.V. All rights reserved.
