Abstract

Four new coordination polymers, {[Zn(3-PBI)(H2O)]·2DMF}n (1), [Cd(3-PBI)(DMF)]n (2), {[Zn44-O)(4-PBI)3]·3DMF}n (3), {[Cd4(4-PBI)4(H2O)6]·13H2O}n (4), have been constructed from two isomeric flexible multi-carboxylate ligands, 3-H2PBI = 5-(3-(pyridin-3-yl)benzamido)isophthalic acid and 4-H2PBI = 5-(3-(pyridin-4-yl)benzamido)isophthalic acid. Structural analysis reveals that compound 1 is a one-dimensional (1D) ladder-like chain assembled by Zn(ii) ions and 3-PBI2- ligands, which further extend into a 3D supramolecular structure through π⋯π stacking and interlayer (O-H⋯O) hydrogen bonding interactions. In compound 2, Cd2+ metal ions are connected by carboxylate groups to form [Cd2(COO)4] secondary building units (SBUs). The whole framework possesses a quadrilateral channel and constitutes a unique 3D (3,6)-connected rutile net with the Schläfli symbol of (42·610·83)(4·62)2. As for 3, Zn(ii) ions are bridged by one μ4-O and six carboxylate groups to form a tetranuclear [Zn44-O)(COO)6] cluster, resulting in a rare (3,9)-connected 3D network. Compound 4 has an appealing 2D layered architecture involving two distinct topologies in the crystal structure, stacking in an unusual ABBABB mode (where A represents (4·82) topology and B denotes kgd topology). Moreover, compound 2 is prepared as a support for active selenium through a melt-diffusion method. The obtained Cd-CP/Se electrode can be tested for lithium-selenium batteries and shows an initial capacity of 514 mA h g-1 and a reversible capacity of 200 mA h g-1 at 1C after 500 cycles. The good storage performance of Cd-CP/Se demonstrates it to be a prospective cathode material for lithium-selenium batteries.
