3-DIMENSIONAL ORGANIC INORGANIC HYBRID MATERIALS CONSTRUCTED FROM ONE-DIMENSIONAL COPPER DIAMINE COORDINATION POLYMERS LINKED BY BRIDGING OXOANION TETRAHEDRA - [CU(DPE)(MOO4)] AND [CU(DPE)(SO4)(H2O)] (DPE EQUALS 1,2-TRANS-(4-PYRIDYL)ETHENE)/

The hydrothermal reaction of CuSO4 . 5H(2)O, dpe, MoO3, and water in t he mole ratio 1:2:2:900 at 120 degrees C for 111 h yielded [Cu(dpe)(Mo O4)] (1). Upon omitting the molybdate component, the reaction of CuSO4 . 5H(2)O, dpe and water in the mole ratio 1:1:1111 at 120 degrees C f or 72 h yielded [Cu(dpe)(SO4)(H2O)] (2). The structure of 1 is constru cted from {Cu(dpe)}(2+) linear chains bridged through {MoO4}(2-) tetra hedra into a three-dimensional framework, while that of 2 consists of {Cu(dpe)}(2+) chains bridged through {SO4}(2-) tetrahedra. However, wh ile the {MoO4}(2-) units of 1 adopt the eta(3)-coordination mode, each linking three adjacent chains, the {SO4}(2-) units of 2 assume eta(2) -coordination and bridge only two neighboring chains. These difference s in {EO4}(2-) coordination modes are reflected in the dramatically di fferent three-dimensional structures displayed by 1 and 2.
