Abstract

Tuning the coordination sites of two isomeric semirigid ligands, 5-(4-pyridin-3-yl-benzoylamino)isophthalic acid (3-HPBI) and 5-(4-pyridin-4-yl-benzoylamino)isophthalic acid (4-HPBI), afforded six new coordination polymers (CPs), [Zn(3-PBI)(HO)] (), {[Mn(3-PBI)(HO)]·DMF·2HO} (), {[Gd(3-PBI)(HO)]·DMF·3HO} (), {[Zn(4-PBI)]·HO} (), {[Mn(4-PBI)(HO)]·4HO} (), and {(MeNH)[Gd(4-PBI)]·HO} (). Structural analysis shows that consists of 2D honeycomb (6,3) net, three sets of networks interlace mutually, generating an unexpected 2D + 2D + 2D → 3D polycatenating interesting system. exhibits a 3D topology. presents a unique 3D with 3,3,6T13 network topology. possesses 3D 2-fold interpenetrated structure with topology. presents an alluring 2D architecture comprising two distinct topologies ( and ), stacked arrangement in an unexpected ABBABB mode. displays 2D (4,4)-grid network. A differentiation of these structural features indicate that coordination connectivity of metals, together with binding modes of two ligands are accountable for the fascinating structural contrast. In addition, and were then transformed into MnO via a simple heat treatment. Electrochemical test results show that both of the obtained MnO moieties exhibit stable lithium storage properties and excellent rate capabilities.
