Vanadium Polyoxoanions within Coordination Polymers Based on a Macrocyclic Nickel Complex: Structural Diversities and Single‐Crystal to Single‐Crystal Transformation

Abstract

, and [(NiL) 4 (V 10 O 29 )] n (5), have been obtained by the reaction of the macrocyclic nickel complex [NiL](ClO 4 ) 2 (L = 1,4,8,11-tetraazacyclotetradecane) with NH 4 VO 3 under different conditions. Single-crystal X-ray diffraction analyses revealed that the [VO 3 ]anion assumes diverse species and structures in these five coor- [a]

“… 19 − 22 Selection of an appropriate solvent as well as time and temperature of the reaction is not less important. 23 − 25 Also, the presence and concentration of an additional electrolyte may strongly influence the course of the crystallization process, by increasing the ionic strength of the solution. It often results in the increase of the building blocks’ solubility and the slower crystallization process, which can lead to the formation of larger and better quality product crystals.…”

“…The construction of molecule-based materials is usually carried out using the building block self-assembly method. By taking into account the building block characteristics, in particular the geometry, charge, coordination environment of metal centers, and potential ability to create new coordination connections, certain predictions regarding the product dimensionality and topology can be made. , In addition to strong coordination bonds, the presence of weaker intermolecular interactions including hydrogen bonds and/or pi-stacking, greatly affects the resulting product structure. − Selection of an appropriate solvent as well as time and temperature of the reaction is not less important. − Also, the presence and concentration of an additional electrolyte may strongly influence the course of the crystallization process, by increasing the ionic strength of the solution.
