Metal‐Anion Coordination and Linker‐Anion Hydrogen Bonding in the Construction of Metal‐Organic Frameworks from Bipyrazole

Abstract Two new two‐dimensional frameworks based on packing of square grids, Cu(Me 4 bpz) 2 (NO 3 ) 2 ( 1 ) and Zn(Me 4 bpz)(SO 4 ) ( 2 ) (Me 4 bpz=3,3′,5,5′‐tetramethyl‐4,4′‐bipyrazole), have been synthesized by mild solvothermal method. In addition to the major metal‐organic linker coordination, they allow us to study how the metal‐inorganic anion coordination and organic linker‐inorganic anion hydrogen bonding affect the resulting structures during the framework assembly.
