There total 8 articles about which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

Coordination geometry of lead carboxylates - Spectroscopic and crystallographic evidence

10.1039/c4dt03075c

The research investigates the coordination geometry of lead carboxylates, focusing on how the structure varies with the length of the carboxylate chain. The study uses a combination of solid-state nuclear magnetic resonance (NMR) spectroscopy, infrared spectroscopy, and X-ray diffraction to analyze a series of lead carboxylates ranging from lead hexanoate (C6) to lead octadecanoate (C18). The purpose is to understand the structural differences between short-chain and long-chain lead carboxylates, which is crucial for applications in areas like paint conservation and the design of chelating agents.
