Stepwise assembly of homochiral coordination polymers based on the precursor of an enantiopure Yb _3Mn _6 cluster

摘要

Two homochiral coordination polymers, namely, [Yb _3 ~(III)Mn _6 ~(III)(L) _6(μ _2-OMe) 6(isonicotinate) _2(HOMe) _2][Yb _3 ~(III)Mn _6 ~(III)(L) _6(μ _2-OMe) _6(isonicotinate) _2(HOMe) _4](NO _3) _2·6MeOH·12H _2O (5) (H 3L = (S,E)-4-(2-hydroxybenzylideneamino)-2-hydroxybutanoic acid) and [Yb_3 ~(III)Mn _6 ~(III)Na(L) _6(μ _2-OMe) _6(OOCH) _3]I·17H _2O (6), have been constructed by utilizing a stable enantiopure [Yb _3 ~(III)Mn _6 ~(III)(L) _6(μ _2-OMe) _6] ~(3+) (Yb _3Mn _6) cluster as a precursor.
