| - Reaction of a Langmuir monolayer of an amphiphilic pentacyanoferrate(3+) complex with Ni2+ions from the subphase results in the formation of a two-dimensional iron−nickel cyanide-bridged networkat the air−water interface. The network can be transferred to various supports to form monolayer or multilayerlamellar films by the Langmuir−Blodgett (LB) technique. The same network does not form fromhomogeneous reaction conditions. Therefore, the results demonstrate the potential utility of an interfaceas a structure director in the assembly of low dimensional coordinate covalent network solids. Characterization of the LB film extended networks by X-ray photoelectron spectroscopy (XPS), FT-IR spectroscopy,SQUID magnetometry, X-ray absorption fine structure (XAFS), and grazing incidence synchrotron X-raydiffraction (GIXD) revealed a face-centered square grid structure with an average domain size of 3600 Å2.Magnetic measurements indicated that the network undergoes a transition to a ferromagnetic state belowa Tc of 8 K.
