A novel hexaaquacopper (II) complex:[3 + 3] distorted octahedral coordination and inorganic-organic interface

摘要

A novel hexaaquacopper (II) complex Cu(H_2O)_6(OPCy_3)_6(BF_4)_2 (OPCy_3 = tricyclohexylphosphine oxygen) was synthesized and structure characterized.In the crystal,the six water molecules coordinated to the copper atom center are classed to two groups which are different from [4+2] or [2+2+2] of the hexaaquacopper (II) distorted octahedral coordinations found before.An outstanding character of the complex is that there is an inorganic-organic interface through hydrogen bonding in the complex.
