The invention concerns cationic complexes of Technetium-99m with bidentate ligands (L), including complexes having the formulae [Tc(NO) X L.sub.2 ].sup.+ and [Tc L.sub.3 ].sup.+, which are of interest as heart imaging agents. The ligands are characterized by having the formula Y.sub.2 QZQY.sub.2, where each Q is phosphorus or arsenic, Z is a 2 or 3 carbon atom linking group, and at least one of the groups Y and Z includes at least one --COC--ether group.
该发明涉及锝-99m与双齿配体(L)形成的阳离子络合物,包括具有公式[Tc(NO)XL.sub.2].sup.+和[TcL.sub.3].sup.+的络合物,这些络合物作为心脏成像剂具有兴趣。这些配体的特征是具有公式Y.sub.2QZQY.sub.2,其中每个Q是磷或砷,Z是一个含有2或3个碳原子的连接基团,至少其中一个Y和Z组包含至少一个--COC--醚基团。
