The unclear assembly mechanism seriously hinders the preparation and application of 3d-4f heterometallic clusters. Two new nanoclusters [Dy2Mn4(HL)4(OAc)6]·5EtOH·H2O (1) [Gd2Mn4(HL)4(OAc)6]·4EtOH·4H2O (2) were obtained from in situ condensation reaction 3-amino-1,2-propanediol with 2-hydroxy-1-naphthaldehyde. intermediate species cluster 1 synthesis process tracked by time-dependent high-resolution electrospray ionization mass spectrometry (HRESI-MS), further revealing possible formation (Dy → DyL2 →DyMn2L2 DyMn3L2 DyMn4L3 Dy2Mn4L4). Magnetic studies indicated that antiferromagnet LnIII-MnII (Ln = DyIII GdIII) interaction was operative both titled Furthermore, performance clusters regulated adjusting type rare earth ions (DyIII GdIII). research results showed 2 containing GdIII exhibited an excellent longitudinal relaxation rate (r1) 1.95 mM-1 s-1 under 0.5 T a relatively suitable r2/r1 value (3.88), which it can be used as efficient T1 MR contrast agent. Cluster displayed antipathogenic activities against clinical MRSA strain MIC 32 μg/mL. This work not only provided reference for but also confirmed its potential biomedical field.

Three new asymmetrically coordinated lanthanide derivatives based on the bicompartmental salen-type ligands N,N′-bis(3-ethoxysalicylidene)propylene-1,3-diamine (H2EtOsalpr) and 3-ethoxysalicylaldehyde (HEtvain) have been synthesized structurally photophysically characterized. All compounds show dimeric structures of general formula [Ln(H2EtOsalpr)(NO3)2(Etvain)]2 (Ln = Nd, Eu, Dy), with each ligand bridging two ions. The Etvain comes from H2EtOsalpr decomposition being to corresponding lanthanide. Nd(III) derivative shows fluorescence emission in NIR region, but for Eu(III) Dy(III) compounds, only a broad band, attributed emission, was observed.
