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

摘要

Two luminescent coordination compounds,[Cu(Pz)]_3 (1) and [Cu_2(Bpz)]_n (2),were isolated from solvothermal reactions of Cu(NO_3)_2 with 3,5-dimethylpyrazole (HPz) and 3,3',5,5'-tetra-methyl-4,4'-bipyrazole (H_2Bpz) respectively in the presence of NH_3,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.
