ABSTRACT:
Compounds of the general formula I: ##STR1## wherein R.sup.1 signifies a COOX group or the group ##STR2## R.sup.2 and R.sup.3 are the same or different and signify a hydrogen atom, a lower straight- or branched-chain, hydrocarbon radical, a phenyl or benzyl group or either R.sup.2 or R.sup.3 signifies the group ##STR3## or R.sup.2 or R.sup.3 together signify a trimethylene or tetramethylene radical, R.sup.4 represents a straight- or branched-chain mono- or poly-hydroxyalkyl radical, R.sup.5 represents a hydrocarbon atom, a lower straight- or branched-chain, optionally mono- or poly-hydroxylated, hydrocarbon radical, Q signifies an oxygen or sulfur atom or the group ##STR4## and X represents hydrogen atoms and/or metal ion equivalents, and their salts with physiologically harmless organic bases, are valuable complexing agents, complexes and complex salts for diagnostic imaging.
