摘要
A new 2-D cluster-based polymer {[(Cu6Cu6L6)-Cu-I-L-II(H2O)(3)-(CH3OH)(6)]center dot 5H(2)O center dot 3CH(3)OH}(n) (2) (H3L = C6H5C(O)NHC-(S)NHCH2COOH) containing unique mixed-valence [(Cu6Cu6L6)-Cu-I-L-II] subunits was synthesized by reaction of single crystals of [Ln(2)(H2L)(4)(Phen)(2)(NO3)(2)] (Ln = Pr (1a), Nd (1b) or Ho (1c)) (Phen = 1,10-phenanthroline) with copper(II) acetate in aqueous DMF. Interestingly, cation-exchanged products {[(Cu6Cu65Zn)-Cu-I-Zn-II(H2O)(3)(CH3OH)(6)]center dot 5H(2)O center dot 3CH(3)OH}(n) (3) or {[(Cu6Cu64Co2)-Cu-I-Co-II(H2O)(3)(CH3OH)(6)]center dot 5H(2)O center dot 3CH(3)OH}(n) (4) were obtained from single crystals of 2 and the appropriate M(NO3)(2) (M = Zn or Co) in H2O.
