摘要

Three new coordination polymers [MnL¹(dca)₂]_n (1) (L¹ = 1-(2-pyridyl)-4-(2-pyrazinyl)-4-amino-1-methyl-2,3-diaza-1,3-butadiene, dca =N(CN)₂^- ), [CdL²(dca)₂]_n (2) (L² = 1-(2-pyridyl)- 4-(2-pyrazinyl)-4-amino-2,3-diaza-1,3-butadiene) and [CdL¹(dca)₂]_n (3) have been synthesized, structurally and/or magnetically characterized. In these isostructural compounds, metal ions of octahedral geometry are bridged by double μ_1,5-mode dca ions and further interlinked into a 1D ladder-type chain by two single μ_1,5-mode dca ions with the Schiff-base ligands acting only as bidentate ligands. Variable temperature magnetic studies have shown that the coupling interaction between Mn(II) centers of the ladder-type Mn-dca chains is weakly antiferromagnetic.
