Design and solvothermal synthesis of luminescent copper(I)-pyrazolate coordination oligomer and polymer frameworks

Two luminescent coordination compounds, [Cu(Pz)](3) ( 1) and [Cu-2(Bpz)](n) ( 2), were isolated from solvothermal reactions of Cu(NO3)(2) with 3,5-dimethylpyrazole (HPz) and 3,3',5,5'-tetramethyl-4,4'- bipyrazole (H(2)Bpz) respectively in the presence of NH3, of which 1 was revealed to be a planar trimer and 2 a three-dimensional framework, presenting a rare 3-connected binodal (6(2).10)(6.10(2)) topology and eight-fold interpenetration.
