Regulation of deprotonation of 3,3-di(1H-tetrazol-5-yl)pentanedioic acid: Solvothermal synthesis of La(III) and heterometallic La(III)/Cu(II) compounds for ablation of A549 cells

3,3-di(1H-tetrazol-5-yl)pentanedioic acid (H4dtzpda) show different valence when reacted with La3+ or bimetallic La3+/Cu2+. PEG-5000 coated nanoparticles have a great potential as an anticancer agent.175
