Maleimide groups are used extensively in bioconjugation reactions, but limited mechanistic studies are available regarding their hydrolysis reactions. In this paper, five single-crystal structures related with the reaction of four-step hydrolytic degradation of N,N′-ethylenedimaleimide have been investigated. On the basis of experimental results, the reaction mechanisms without or with water catalysis are proposed, which could provide some enlightenment into the study of similar hydrolytic degradations.

Dimeric (hydrated and anhydrated) complexes of Cu(II) with N,N'-bis(3-carboxy-1-oxo-2-prop-2-enyl)ethylenediamine (BCOPENH2, A) and N,N'-bis(2-carboxy-1-oxo-phenylenyl)ethylenediamine (BCOPHENH2, B) have been prepared and characerised by elemental analysis, magnetic susceptibility measurements, EPR, thermal and spectral (IR, UV/Vis) studies. EPR parameters and magnetic behaviour indicates that the complexes are antiferromagnetic in nature and most likely adopt the typical carboxylate cage structure. Interesting amide bonding patterns have been observed and various EPR parameters have been evaluated on the basis of these studies, tentative probable structures of the complexes have been proposed.

A few complexes of Co(II), Ni(II), Cu(II) and Pd(II) with a tetradentate ligand N,N'-ethylene-bis-(3-carboxypropenamide) and a bidentate ligand benz--2-carboxymethyl-1,3,4-thiolactam have been synthesised and characterized by elemental analyses, conductance, thermal, magnetic and IR, NMR and electronic spectral studies.
