Abstract
- The formation, crystal structures, and properties of a series of three-dimensional (3-D) CuII coordination polymers, {[Cu(L)2(H2O)2](PF6)2(H2O)1.25}n (1), {[CuL(N3)2](H2O)1.5}n (2), and {[CuL(H2O)(SO4)](H2O)2}n (3), with an angular bridging ligand 2,5-bis(4-pyridyl)-1,3,4-oxadiazole (L) are reported. Complex 1 crystallizes in the tetragonal /41/a space group (a = b = 13.462(2) Å, c = 46.47(1) Å, Z = 8), complex 2 in the orthorhombic Pna21 space group (a = 6.379(2) Å, b = 10.060(3) Å, c = 27.232(9) A, Z = 4), and complex 3 in the orthorhombic P212121 space group (a = 5.510(2) Å, b = 10.576(4) ,Å, c = 28.34(1) Å, Z = 4). Different polymeric frameworks are obtained by only varying the counterions. These include the 2-fold interpenetrated diamondoid structure of 1, the acentric α-Po network of 2, and the chiral open framework of 3 with (6³).(69.8) topology. The interesting anion-exchange, porous, and magnetic properties of these coordination supramolecules have been investigated in detail. [ABSTRACT FROM AUTHOR]
