Poly[(μ3-5-tert-butylbenzene-1,3-dicarboxylato) dipyridinecobalt(II)]

초록

In the title compound, [Co(C12H12O 4)(C5H5N)2]n, the Co II cation is coordinated by four O atoms from three 5-tert-butylbenzene-1,3-dicarboxylate anions and two N atoms from pyridine molecules in a distorted octahedral geometry. One carboxylate group of the anionic ligand chelates a CoII cation while another carboxylate group bridges two CoII cations, resulting in a polymeric layer parallel to (101). Weak C - H⋯O hydrogen bonds occur between adjacent polymeric layers. In the crystal, one of pyridine molecules is equally disordered over two positions.
