Organic ligands examples
WitrynaMany simple organic ligands form strong bridges between metal centers. Many common examples include organic derivatives of the above inorganic ligands (R = alkyl, aryl): OR −, SR −, NR − 2, NR2− (imido), PR− 2 (phosphido, note the ambiguity with the preceding entry), PR2− (phosphinidino), and many more. Examples [ edit] Witryna28 mar 2024 · Therefore it is important to select metals and organic ligands that are biocompatible when constructing MOFs. For example metals such as Zinc and Iron metals, used in this work, are reported to have low toxicity with oral lethal dose 50 (LD50) values from 350–450 mg kg −1 [31, 35].
