Abstract

The diamagnetic two-dimensional Hofmann-type metal-organic framework [Zn^II(2-mpz)₂Ni(CN)₄] has been successfully synthesized along with its isostructural hysteretic spin-crossover Fe^II analogue in the form of both bulk microcrystalline powder and nanoparticles. Detailed atomic force microscopy topographic study revealed a nanogrowth relationship between the height and length of the nanoparticle.
