Bottom‐Up Synthesis of Monodispersed Single‐Crystalline Cyano‐Bridged Coordination Polymer Nanoflakes

A two-dimensional morphology characterizes the nanoflakes that are obtained in the bottom-up synthesis of a single-crystalline coordination polymer, Ni(H2O)2[Ni(CN)4]⋅x H2O. The 10 nm-thick nanoflakes are well-dispersed in solution and have a very high accessible surface area (240 m2 g−1). Thermal treatment leads to nanoporous NiO with retention of the original flake morphology.
