  Ligand mediated structural diversity and role of different weak interactions in molecular self-assembly of a series of copper(II)–sodium(I) Schiff-base heterometallic complexes

  摘要：

  We report three new Cu-Na heterometallic complexes namely [Cu(L-1(2)) Na(NO3)(CH3OH)] (1), [Cu(L-22)Na(NO3) (CH3OH)] (2) and [Cu Na (L-33)] n (3) where the topology of the synthon is directly governed by the p-p interaction involving the Cu-Schiff base chelate rings. The crystal structure analysis also reveals how the systematic variation in the ligand framework influences the supramolecular assembly and the mutual cooperation of different pi-forces and the hydrogen bonding forces in the supramolecular assembly. The pi-forces are more important than the hydrogen bonding forces in such compounds is evident from the supramolecular assembly of compound 3. Most interesting revelation of the studies are the presence of relatively uncommon pi-forces such as chelate ring pi...pi chelate ring and metal-pi interactions in the supramolecular architecture of the complexes. The analysis of the supramolecular assembly of the complexes 1-3 reveals that metal-chelate rings play prominent role in the organization of the molecular complexes and should seriously consider along with other p-stacking forces.

  A vanadium(V)–cerium(IV) trinuclear complex, [VVO2(L1)}2CeIV] (1) (H3L1: N,N′-bis-3-ethoxysalicylidene-2-hydroxy-1,3-propanediamine), was prepared by the reaction of [VIVO(acac)2] and [CeIII(acac)3]·3H2O with H3L1 in CH3CN, followed by oxidation of the product in air. The structure of complex 1 was determined by X-ray crystal structure analysis. The complex has a VV–CeIV–VV trinuclear structure with two dioxovanadium(V) moieties on each side of the cerium(IV) moiety. Complex 1 has two L1 ligands to form a trinuclear structure. The basal oxo atoms of the dioxovanadium(V) moieties are coordinated to the cerium atom with Ce–O distances of 2.322(3) and 2.343(3) Å. The apical two non-coordinating oxo atoms are oriented to the same direction to form an endo structure. IR data of complex 1 show V=O stretching bands at 975 cm−1 for the apical non-coordinated oxo atoms and 802 cm−1 for the basal coordinated oxo atoms. The cyclic voltammogram of complex 1 in CH3CN shows a quasi-reversible two-electron redox couple with E1/2 = −0.60 V vs Fc/Fc+.

  通过[VIVO(acac)2]和[CeIII(acac)3]-3H2O与H3L1在CH3CN中反应，然后在空气中氧化产物，制备了钒(V)-铈(IV)三核配合物[VVO2(L1)}2CeIV](1)（H3L1：N,N′-双-3-乙氧基水杨酰-2-羟基-1,3-丙二胺）。复合物 1 的结构是通过 X 射线晶体结构分析确定的。该复合物具有 VV-CeIV-VV 三核结构，铈（IV）分子两侧各有两个二氧钒（V）分子。配合物 1 有两个 L1 配体，形成三核结构。二氧钒（V）分子基部的氧原子与铈原子配位，Ce-O 间距分别为 2.322(3) Å 和 2.343(3) Å。复合物 1 的红外数据显示，顶端非配位氧原子的 V=O 伸展带为 975 cm-1，基底配位氧原子的 V=O 伸展带为 802 cm-1。复合物 1 在 CH3CN 中的循环伏安图显示出准可逆的双电子氧化还原耦合，E1/2 = -0.60 V vs Fc/Fc+。
