The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Two complexes of copper(ii) salts with 5-amino-3-(pyrid-2-yl)-1H-pyrazole, the prototype for a new class of ditopic ligand

Abstract

The synthesis and crystallographic characterization of two copper salt complexes of ditopic ligand is examined. The result shows that ligand L can chelate to both the cation and anion of a transition metal salt. The copper ligand bond lengths in the two complexes lie within the usual ranges. A third hydrogen bond involves the other L ligand from a symmetry related complex molecule, which associates with the anion in monodentate fashion through its NH2 group. The functionalization of the amine or pyrazole moieties in L with additional hydrogen bond donors and /or hydrophobic substituents leads to a variety of new ditopic ligand geometries.
