Abstract

We report the high NH₃ uptake in a series of copper-carboxylate materials, namely MFM-100, MFM-101, MFM-102, MFM-126, MFM-127, MFM-190(F), MFM-170, and Cu-MOP-1a. At 273 K and 1 bar, MFM-101 shows an exceptional uptake of 21.9 mmol g⁻¹. The presence of Cu(II)⋯NH₃ interactions and changes in coordination at the [Cu₂(O₂CR)₄] paddlewheel are analysed and discussed.
