The authors report the two-step synthesis of a chiral rod-like metal-organic framework (MOF). The chem. approach consists on the use of a previously prepared oxamato-based homochiral hexanuclear wheel, the ligand being a derivative of the natural amino acid L-alanine, (Me4N)6{CuII6[(S)-alama]6}·10H2O (1) [where (S)-alama = (S)-N-(Et oxoacetate)alanine]. The anionic hexacopper(II) wheels, stabilized by the presence of templating tetramethylammonium countercations, disassemble in the presence of cationic square-planar [Ni(cyclam)]2+ complexes to yield, after a supramol. reorganization process that involves axial coordination of the [Ni(cyclam)]2+ cations through the free carbonyl groups of the copper(II) moieties, a neutral chiral rod-like, three-dimensional (3D) MOF [Ni(cyclam)][Cu(S)-alama]2·16H2O (2). The resulting MOF constitutes one of the few examples where such a high-nuclearity metal complex was used as precursor for the construction of rod-like MOFs. In addition to this study using Ethyl oxalyl monochloride, there are many other studies that have used Ethyl oxalyl monochloride(cas: 4755-77-5SDS of cas: 4755-77-5) was used in this study.
Ethyl oxalyl monochloride(cas: 4755-77-5) belongs to acyl chlorides. Lacking the ability to form hydrogen bonds, acyl chlorides have lower boiling and melting points than similar carboxylic acids. For example, acetic acid boils at 118 °C, whereas acetyl chloride boils at 51 °C. Like most carbonyl compounds, infrared spectroscopy reveals a band near 1750 cm−1.SDS of cas: 4755-77-5
