NO3−-induced Salen-based Zn2Yb2 complex with good NIR luminescent property

Effect of diamagnetic Zn(ii) ions on the SMM properties of a series of trinuclear ZnDy2 and tetranuclear Zn2Dy2 (LnIII = Dy, Tb, Gd) complexes: combined experimental and theoretical studies

“…Varying topology and different structural cores of several tetranuclear Ln–Zn complexes are reported in the literature. 43,54,75–86…”

Alternating copolymerization of CHO and MA catalyzed by the hetero-bimetallic Zn-Yb-Salen complex

“…As to the Yb 3+ (Yb1) ion, it is eight-coordinate and gives a square anti-prismatic pattern, where besides four O atoms from the outer O 2 O 2 moiety of the ligand (L) 2− , another four O atoms (O7, O8, O9 and O11) are contributed from the bidentate μ 2 -OAc − anion, another mono-dentate μ 1 -OAc − anion and one coordinated H 2 O molecule, respectively. It is worth noting that the OAc − -induced hetero-bimetallic host structure in 1⋅MeOH is incomparable with Cl − -dependent Zn 2 Ln [14] or NO 3 − -dependent Zn 2 Ln 2 [15], OAc − and NO 3 − -dependent ZnLn [16], Cl − and N 3 − -dependent Zn 2 Ln and Zn 2 Ln 3 frameworks [17] due to actual anion-controlling. Moreover, lanthanide contraction from Nd 3+ to Yb 3+ ion renders a shorter Zn 2+ ⋯ Yb 3+ separation 3.4590(6) Å in 1 ⋅ MeOH, from which the OAc − bridging between them is damaged for the formation of ZnYb while not Zn 2 Nd unit [18].…”
