Abstract

The reaction of Cu(NO3)2 containing NH 4PF6 with btp ligands produced a new polymeric compound 1 containing Cu(H2O)22+ and Cu(NO3)2 units alternatively bridged by btp ligands with H-bonds between copper-bonded water and nitrate oxygen atoms. Crystal Data: M=1465.97, space group P2/n, a=11.6300(3) Å, b=12.8000(4) Å, c=19.2960(6) Å, β=98.6200(19)°, V=2840.03(15) Å3, Z=2, μ=0.926 mm-1, Dc=1.714 Mg/m3, R=0.0629, wR=0.1614. The polymeric compound 1 has shown the heterogeneous catalytic activity for the ring opening of epoxides under mild conditions. This catalyst system appears to be an efficient, mild, and easily recyclable method for the alcoholysis of epoxides. In addition, the heterogeneous catalyst 1 has, surprisingly, shown even better catalytic activity than copper salt system in homogeneous condition.
