Hydrogen-Bond Network of Dimeric Copper Complex of Vanillic Acid (HVA), [Cu(VA)₂(H₂O)]₂

Abstract

The crystal structure of the title complex was first determined, showing a dimeric copper form with the four carboxylate groups. The Cu···Cu distance is short, associated with the hydrogen bond link of the apically coordinated water molecules with the nearest neighbor vanillic hydroxyl group. The hydrogen bond links afford an infinite 3-D network.

Key Words:

• crystal structure
• vanillic acid
• hydrogen bond
