Synthesis and structure of a copper(II) melamine complex, [Cu(C₃H₆N₆)(µ-OCH₃)(ONO₂)(HOCH₃)]₂, with direct Cu–melamine coordination

Abstract

The title compound, which was obtained by an in situ conversion of diacetylmelamine to melamine in the presence of copper(II) nitrate, appears to be the first structurally characterised example of a melamine complex with direct metal–melamine bonding; complexes are linked via N–H  · · ·  O and O–H  · · ·  N hydrogen bonds to form sheets.
