Abstract

The hydrothermal reaction of CuSO4·5H2O, dpe, MoO3, and water in the mole ratio 1:2: 2:900 at 120 °C for 111 h yielded [Cu(dpe)(MoO4)] (1). Upon omitting the molybdate component, the reaction of CuS04·5H2O, dpe and water in the mole ratio 1:1:1111 at 120 °C for 72 h yielded [Cu(dpe)(SO4)(H2O)] (2). The structure of 1 is constructed from {Cu(dpe)}2+ linear chains bridged through {MoO4}2- tetrahedra into a three-dimensional framework, while that of 2 consists of {Cu(dpe)}2+ chains bridged through {SO4}2- tetrahedra. However, while the (MoO4}2- units of 1 adopt the η3-coordination mode, each linking three adjacent chains, the {SO4}2- units of 2 assume η2-coordination and bridge only two neighboring chains. These differences in {EO4}2- coordination modes are reflected in the dramatically different three-dimensional structures displayed by 1 and 2.
