Resum
The employment of three structurally related Schiff bases H(2)L1, H(2)L2, and H(3)L3 with zinc and lanthanide salts under various reaction conditions, gave four families of compounds formulated as [Zn(2)(II)Ln(2)(III)(L1)(4)(EtOH)(6)][ClO4](2) (1-3), [Zn(5)(II)Ln(OH)(L1)(6)(H2O)] (4-6), [Zn(4)(II)Ln(2)(III)(OH)(2)(L2)(4) (OAc)(2)(NO3)(2)(DMF)3]center dot DMF (7-9), and [Zn(2)(II)Ln(2)(III)(L3)(2)(NO3)(2) (CO3)(2)(CH3OH)(2)] (10-12) with robust and novel topologies. Synthetic aspects are discussed. A comprehensive topological analysis of all reported Zn-II/Ln(III) CCs with a core nuclearity of four and above is presented and identifies that families (4-6) and (7-9) are the first examples of the 2,3,4M6-1 motif in Zn-II/Ln(III) chemistry. Magnetic studies are presented for the Dy-II analogues (1, 7, and 10) are presented, 7 demonstrates field -induced slow relaxation of the magnetization. Fluorescence studies are also discussed.
