catena-Poly[[bis(nitrato-κ2 O,O′)cobalt(II)]-μ-4,4′-bis(pyrazol-1-ylmethyl)biphenyl-κ2 N 2:N 2′]
In the title compound, [Co(NO3)2(C20H18N4)]n, the CoII atom lies on a crystallographic twofold axis and the coordination geometry can be considered as a slightly distorted tetrahedron defined by two O atoms from two nitrate groups and two N atoms from two ligand molecules. A distorted octahedron may be assumed when two of the symmetry-related nitrate O atoms with Co—O distances of 2.3449 (19) Å are added to the coordination environment. Another twofold axis, passing through the middle of the biphenyl bonds, is observed in the crystal structure. A chain is built up by the ligands linking the CoII ions along [101]
