A series of lanthanide anionic metal-organic frameworks, [NH 2(CH 3) 2][Ln(MDIP)(H 2O)] (Ln = Pr (1), Nd (2), Sm (3), Eu (4), Gd (5), Tb (6), Dy (7); H 4MDIP = methylenediisophthalic acid) and [NH 2(CH 3) 2][Ln(MDIP)(H 2O)]•0.5NH(CH 3) 2 (Ln = Er (8), Tm (9), Yb (10)), have been synthesized and characterized. In compounds 1-7, the adjacent Ln 3+ ions are intraconnected to form infinite metal-carboxylate oxygen chain-shaped building blocks along the [001] direction. In compounds 8-10, MDIP ligands bridge dinuclear lanthanide centers to form three-dimensional frameworks which can be rationalized as a (4,8)-connected topological net with the Schläfli symbol of (4 10.6 14.8 4)(4 5.6) 2. Dimethylamine cations occupy the vacancy of all the compounds as counterions. The photophysical properties of trivalent Pr, Nd, Sm, Eu, Tb, Dy, Er, Yb compounds at room temperature were investigated and showed that MDIP is an efficient sensitizer of the luminescence of both the Tb 3+ ion emitting visible light and the Yb 3+ ion emitting in the near-IR. Antiferromagnetic interactions between Gd 3+ ions were observed from magnetic susceptibility data.
