Synthesis and Crystal Structures of Two New Supramolecular Complexes: [Cu(tmbpm)(ox)(H_2O)]·4H_2O and [Zn(tmbpm)_2(H_2O)]·(ClO_4)_2·5H_2O

摘要

Two new 3D supramolecular complexes, [Cu(tmbpm) (ox)(H_2O)]·4H_2O (1) and [Zn(tmbpm)_2(H_2O)]·(ClO_4)_2·5H_2O (2) (tmbpm = 4,4',6,6'-tetramethyl-2,2'-bipyrimidine, ox = C_2O_4~(2-)), have been synthesized and structurally characterized by elemental analysis, IR spectra, and single-crystal X-ray diffraction. Compound 1 is monoclinic, C2/c, a = 22.429(4) ?, b = 7.6501(14) ?, c = 25.866(6) ?, β = 114.630(2)?; and compound 2 is monoclinic, C2, a = 18.854(3) ?, b = 7.7273(14) ?, c = 12.200(2) ?, β = 93.793(2)?. Both compounds 1 and 2 have a mononuclear structure in which the tmbpm ligand adopts bidentate chelating coordination mode. Two 3D supramolecular structures containing 1D water chains are formed via intermolecular O?H···O and O?H···N hydrogen bonds. Supplementary materials are available for this article.
