摘要：

Two 4-(1,2,4-triazol-1-yl)phenol (hptrz)-based transition metal complexes, {[Ni(H2O)(2)(hptrz)(2) (tp)]center dot 2DMF}(n) (1) and [Cu(hptrz)(2)(SCN)(2)]center dot 2H(2)O (2) (H(2)tp=terephthalic acid), have been prepared and characterized by single-crystal and powder X-ray diffractions, elemental analysis, FT-IR spectra, thermogravimertric and luminescence spectra. X-ray diffraction analysis revealed that 1 is a one-dimensional linear chain with octahedral Ni(II) ions extended by bis-unidentate tp(2-) anions; whereas 2 exhibits a centrosymmetric mononuclear entity. The neutral hptrz ligand in the both complexes serves as terminal ligands to complete the metal coordination sphere and to help to assemble the low-dimensional aggregates into a high-dimensional supramolecular architecture by O-H center dot center dot center dot O hydrogen-bonding interactions. Additionally, the complexes display strong emissions in UV region originated from intraligand electronic transfer. CCDC: 746903, 1; 746904, 2.
