Abstract

Hydrothermal reactions of Ln₂(C₂O₄) ₃·9 H₂O and CuCl₂·2 H ₂O with pyridine-2,3-dicarboxylic acid (H₂pdc) in water in the presence of acetic acid lead to two novel three-dimensional lanthanide(III)-copper(I) heterometallic compounds: LnCu(na)₂(C ₂O₄)·1.5 H₂O (Ln = La 1, Ce 2; na = nicotinic acid). Both compounds are isostructural and contain two distinct units of 2D Ln-organic layers and nonlinear [Cu(na)₂]^-, the nonlinear [Cu(na)₂]^- act as pillars and further link the Ln-organic layers, resulting in two heterometallic metal-organic frameworks (MOFs) with two distinct types of channels along the a and c axes. Further structural analysis reveals that 1 is a scarcely reported eight-connected self-penetrating ilc net with dinuclear {Ln₂} subunits as secondary building units. Furthermore, the IR, TGA, PXRD properties were also studied.
