Synthesis, crystal structures, magnetic properties and DFT calculations of nitrate and oxalate complexes with 3,5 dimethyl-1-(2′-pyridyl)-pyrazole-Cu(ii)

Abstract

Newly synthesized uncommon oxalate bridged Cu(ii) chain of formula [Cu(L)(Ox)2(H2O)]n (2) and a mononuclear Cu(ii) complex [Cu(L)(NO3)2] (1) with uncommon π hole interactions are reported and rationalized using DFT calculations.
