Lignin Based Molecular Materials – a Zinc Vanillate with a Hydrogen Bonded 4- and 8-connected Net with a New Topology
Journal article, 2018

Vanillic acid, C8H8O4, is a possible product from a future biorefinery with lignin as raw material. Two coordination compounds with this ligand in two different protonation states were prepared: 1 [Zn(C8H7O4)2(H2O)2] and 2 [Co2(C8H6O4)2(H2O)6] ⋅ 2H2O. Both compounds form extended 3D structures with strong hydrogen bonds. A high symmetry 8- and 4-connected network topology, jus, is found in 1. The dinuclear coordination entity in 2 hints at a potentially useful SBU for MOF synthesis from lignin based bridging ligands.
