ABSTRACT:
##STR1## Metal complex of tetra-aza macrocycles of formula (1) wherein Alk.sup.1, Alk.sup.2, Alk.sup.3 and Alk.sup.4, which may be the same or different, is each a C.sub.1-4 alkylene chain optionally substituted by one or more optionally substituted C.sub.1-6 alkyl groups; and R.sup.1, R.sup.2, R.sup.3 and R.sup.4 which may be the same or different is each a hydrogen atom or a group AlkR.sup.5 where Alk is an optionally substituted straight or branched C.sub.1-6 alkyl group and R.sup.5 is a hydrogen atom or a --CO.sub.2 H,--CONR.sup.6 R.sup.7 [where R.sup.6 and R.sup.7, which may be the same or different, is each a hydrogen atom or a C.sub.1-6 alkyl group] or --P(X.sup.1)(X.sup.2 R.sup.8)R.sup.9 group where X.sup.1 and X.sup.2, which may be the same or different is each an oxygen or sulphur atom, R.sup.8 is a hydrogen atom or an alkyl group and R.sup.9 is an aliphatic, aromatic or heteroaromatic group, with the proviso that at least two of R.sup.1, R.sup.2, R.sup.3 and R.sup.4 is a group -AlkP(X.sup.1)(X.sup.2 R.sup.8)R.sup.9 or one or R.sup.1, R.sup.2, R.sup.3 and R.sup.4 is a group -AlkP(X.sup.1)(X.sup.2 R.sup.8)R.sup.9 and at least one of the remaining groups R.sup.1, R.sup.2, R.sup.3 and R.sup.4 is a group -AlkCO.sub.2 H or -AlkCONR.sup.6 R.sup.7, or a salt thereof, for use as contrast agents in nuclear magnetic resonance imaging are described.
