A novel one-pot synthetic method to produce crystalline tri-octylphosphine (TOP) capped iron phosphide nanoparticles is reported here. Standard method of synthesizing FeP includes preparation of a precursor, sodium phosphide, which is finally reacted with ferric chloride (FeCl3).The methods for synthesizing iron phosphide (FeP), reported so far, rely on the use of toxic red or yellow phosphorus to generate the precursor, Sodium phosphide (Na3P). In present investigation, instead of red or yellow phosphorus, a relatively less toxic substance TOP and sodium metal (Na) have been used to yield Na3P. The synthesized nanoparticles were fully characterized by X-ray diffraction pattern (XRD), Infrared spectroscopy (IR), X-ray photoelectron spectroscopy (XPS), Transmission electron microscopy (TEM) and superconducting quantum interference device (SQUID) analyses. The results showed that the synthesized FeP nanoparticles have the characteristic orthorhombic crystal structures, with the size ～10 nm and the coercivity 70 Oe at RT.

The chemical durability of NASICON (Na//1// plus //xZr//2Si//xP//3// minus //xO//1//2, x equals 0-3) versus molten sodium and sulfur at 600 K has been investigated. Degradation by molten sodium has been observed for phosphorus-containing compositions only

As a potential material for Na-ion battery systems and on the basis of a structural discussion of compounds formerly believed to crystallize in the so-called Na3As type the structure of Na3P has been reinvestigated. Na3P is found to crystallize in the Cu3P type, analogous to Na3As and is described by a three times larger unit cell [P63cm, a = 8.61224(10) ? and c = 8.81949(10) ?] compared to the former model [P63/mmc, a = 4.9512(5) ? and c = 8.7874(13) ?]. As a structural manifestation of this symmetry reduction corrugated layers of Na and P atoms are observed which had formerly to be described as planar. The high purity of the material further enables the determination of its properties, showing mainly semiconducting behavior with a conductivity of 12 S·cm–1 at room temperature.
Solvothermal preparation of tin phosphide nanorods

, p. 675 - 680 (2000)
Tin phosphide nanorods were successfully obtained through a mild and simple solvothermal route. The synthesis was performed through the solvothermal process based on metathesis reaction between SnCl2 and Na3P at 120-140 °C. Reaction conditions including solvent, temperature, and the valence state of raw materials thin salts were important factors to the morphology, crystallization, and purity of nanocrystalline Sn4P3.
Synthesis, Structure and Reactivity of a Cyapho-Cyanamide Salt

We describe a facile synthesis of the cyapho-cyanamide salt [Na(18-crown-6)][N(CN)(CP)] from reaction of [Na(18-crown-6)][PH2] (18-crown-6=1,4,7,10,13,16-hexaoxacyclooctadecane) with dimethyl N-cyanocarbonimidate, (MeO)2C=N(CN). The reaction proceeds with elimination of two equivalents of methanol. Careful tuning of the reaction conditions allowed for the isolation and characterization of the N-cyano(carboximidate)phosphide intermediate [HP{C(OMe)N(CN)}]?. Due to the adverse effects of methanol in these reaction mixtures, a bulk scale synthesis of [Na(18-crown-6)][N(CN)(CP)] could be achieved by addition of a base (LiHMDS) to neutralize the resulting alcohol. Further reactivity studies of this anion reveal that functionalization at the phosphorus atom is viable to yield a new family of cyanide-functionalised phosphorus heterocycles.
