Three in one: TSA, TSA', and SA units in one crystal structure of a yttrium(III) gornplex with a monophosphinated H4dota analogue

Abstract

Elementary cell of the yttrium(III) complex of aminobenzylphosphinic acid DOTA derivative contains three independent complex units having twisted-square (TSA), twisted-square (without bound water molecule, TSA') and square (SA) antiprismatic arrangements
