Self-assembly of hybrid solids consisting of 2D supramolecular networks and intercalated metal complexes

摘要

Hybrid compounds [NaCr(ox)_3]_2[Ni(cyclam)][Ni(cyclam)(H_2O)_2] centre dot 8 H_2O(1)and [NaCr(ox)_3][Cu(tren)(H_2O)] centre dot-3 H_2O(2)are assembled in MeCN/H_2O from the reaction of Na_3[Cr(ox)_3] centre dot 5 H_2O with [Ni(cyclam)](ClO_4)_2 and [Cu(tren)](PF_6)_2,respectively,where cyclam=1,4,8,11-tetraazacyclotetradecane and tren=tris(2-aminoethyl)amine.In 1 and 2,Ni(II)macrocyclic complex and Cu(II)complex,respectively,are intercalated between the anionic 2D layers of [NaCr(ox)_3]_n~(2n-).The magnetic susceptibility data of 1 and 2,measured in the temperature range 5-301 K,indicate weak ferromagnetic interactions(6=1.9 K for 1 and 0.29 K for 2)between the Cr(III)ions in the 2D layers and the intercalated paramagnetic metal complexes.
