Abstract

A new lanthanide-organic framework (LOF) based on a long (21.2 Å) and rigid bis-Gd complex synthon (complex 1) and carbonate anion spacers was discovered. Complex 1 is comprised of two Gd3+ ions complexed with a pyridine tetracarboxylate ligand and a bridging linear 1,4-diethynylbenzene unit. Two water molecules are coordinated to each Gd ion in order to satisfy its high coordination number. Upon crystallization of 1 in ethanolic aqueous sodium bicarbonate, the carbonate anions replace the coordinated water molecules, partially or fully, resulting in the construction of two network types (type A and B). All three oxygen atoms of the carbonate anion are utilized in its function as a spacer between two synthons (complex 1) in the networks, but the chelating oxygen atoms (to Gd3+ ions) and their coordination modes differ in each of the two networks. In addition, the carbonate anions also serve as acceptors for hydrogen bonding (O-H⋯O) with water molecules coordinated to Gd3+ ions in both the networks. While all the synthons adopt a planar conformation in network A, they are backed alternatingly in plane and vertical conformation in network B. Overall, in this new LOF the synthons are packed in cris-cross fashion and tethered by carbonate ion spacers, creating a crystal lattice perforated by 10.6 × 15.6 Å and 18.6 × 15.6 Å wide-open channels.
