Solvothermal synthesis, a new preparative route to mononuclear lanthanide complexes with in situ built N4O2 hexadendate Schiff base. Synthesis and crystal structure of N,N′-bis[(2-salicylideneamino)ethyl]ethane-1,2-diamine nitrato[O,O]Erbium(III) hydrate

Solvothermal synthesis led to a novel Er complex with N,N′-bis[(2-salicylideneamino)ethyl]ethane-1,2-diamine. Its crystal structure can be described by [Er(H2L)(NO3)] units in which Er atom is surrounded with a N4O2 Schiff base and a bidentate image group. These units are linked together by hydrogen bonds through H2O to build infinite chains.
