A Perspective on Molecular Structure andExperimental-Computational Characterization of a Novel Cd(II) Pyridine-TerminalSalamo-like Coordination Polymer

A structurally novel Cd(II) coordination polymer (CP), [Cd(H2L)2(NCS)2]n, has been self-assembled from a newly designed salamo-like ligand H2L bearing double terminal pyridine groups, Cd(II) and KSCN. The Cd(II) ion is not located in the N2O2 cavity of the ligand H2L and forms a six-coordinate octahedral geometrical configuration. Using Cd(II) ion as a node, the undeprotonated salamo-like ligand H2L units extend in space to give a Cd(II)CP with a 2D pore structure. Spectroscopic analysis of the ligand H2L and its Cd(II)CP is performed using IR, UV-Vis and fluorescence spectroscopy. Various short-range interactions in the Cd(II)CP are investigated on the basis of Hirshfeld surfaces analysis.
