Assembly of a 1D coordination polymer through in situ formation of a new ligand by double C-C coupling on CHCl3 under solvothermal conditions.

A rare in situ metal/ligand reaction has been observed during the assembly of a manganese-coordination polymer under solvothermal conditions, which leads to double C-C coupling on CHCl(3) involving cleavage of three C-Cl bonds and the formation of two new C-C bonds at the same carbon center.
