X-Ray crystal structure of {Cu[1,2-bis(4-pyridyl)ethane]2(NO3)2}n: the first example of a coordination polymer that exhibits the NbO 3D network architecture†

Abstract

The coordination polymer {Cu[1,2-bis(4-pyridyl)ethane]₂-(NO₃)₂}_n does not exist as a square grid network, rather it is the first example of a twofold NbO type 3D network. A twofold level of interpenetration does not preclude the presence of 11 × 11 Å channels which contain benzene and methanol guest molecules.
