Abstract

Two hybrid materials, formulated as [NiL]₃[VO₃]₆·2H₂O (1) and [CuL][VO₃]₂·2H₂O (2) (L = 1,8-dibutyl-1,3,6,8,10,13-hexaazacyclotetradecane), were obtained by the reactions of transition metal macrocyclic complexes [ML](ClO₄)₂ (M = Ni, Cu) with NH₄VO₃, characterized by elemental analysis, infrared spectroscopy analysis, thermogravimetric analysis, and X-ray powder diffraction. The single-crystal structures analysis showed that the Ni(II)/Cu(II) atom is coordinated by two oxygen atoms from [VO₄] tetrahedra, plus four nitrogen atoms from L, forming a distorted six-coordinate octahedral coordination geometry. Six [VO₄] tetrahedra form a hexanuclear [V₆O₁₈]⁶⁻ ring by sharing six μ₂-oxygen atoms in compound 1, and the [VO₄] tetrahedra are connected by sharing μ₂-oxygen atoms to form a one-dimensional zigzag chain of [VO₃]_n^n- in compound 2. Compounds 1 and 2 show diverse three-dimensional structures, which are constructed by the connections of hexanuclear [V₆O₁₈]^6- rings with [NiL]²⁺ moieties in compound 1, and [VO₃]_n^n- chains with [CuL]²⁺ moieties in compound 2, respectively.
