Two heteronuclear 3d–4f complexes obtained by salen-type ligand N,N′-bis(2-hydroxy-3-methoxybenzylidene)-1,3-diaminopropane (H2L1) and N,N′-bis(2-hydroxy-3-methoxy benzylidene)-1,2-diaminohexane (H2L2) have been isolated. They are co-crystallized complex [Yb(ZnL1)(OAc)2(H2O)]·[Yb(ZnL1)(OAc)3]·PF6·CH3OH (1), trinuclear complex [Sm(ZnL2)2Cl2(H2O)2]·PF6 (2). In complexes 1 and 2 the anion PF6 called counteranion is not only a role to neutralize overall charge in the solid but also to regulate frameworks. The complexes were structurally characterized by single crystal X-ray crystallographic studies and their photophysical properties were investigated.
