Assembly chemistry of a cadmium(II) complex with cyanometalate anions [Fe(CN)5NO]2−, [Pd(CN)4]2− and [Pt(CN)6]2−
摘要:
Three complexes, namely [Cd(tren)][Fe(CN)(5)NO] (2), [Cd(tren)][Pd(CN)(4)] (3) and [Cd(tren)][Pt(CN)(6)] (4), were prepared via direct reactions of Na-2[Fe(CN)(5)NO], K-2[Pd(CN)(4)] and K-2[Pt(CN)(6)], respectively, with cadmium acetate and tris(2-aminoethyl)amine (tren) in aqueous solution. X-ray structural analysis shows that 2 features a shelf-like structure formed by stacking of the quasi-square building block. Compound 3 is a battlement-like polymer constructed from cyanometalate building blocks and compound 4 represents the first example of a cyano-bridged trinuclear hexacyanoplatinate(IV) complex.
