Thorium phosphide

Compounds with Sc, Y, lanthanoids and actinoids are of three types. Those with composition ME have the (6-coordinated) NaCl structure, whereas M3E4 (and sometimes M4E3) adopt the body-centred thorium phosphide structure (Th3P4) with 8-coordinated M, and ME2 are like ThAsi in which each Th has 9 As neighbours. Most of these compounds are metallic and those of uranium are magnetically ordered. Full details of the structures and properties of the several hundred other transition metal-Group 15 element compounds fall outside the scope of this treatment, but three particularly important structure types should be mentioned because of their widespread occurrence and relation to other structure types, namely C0AS3,... 

The phosphides of titanium and zirconium to which were assigned the formulae TiP and ZrP2 are described as yellow or grey crystalline substances, which conduct electricity. They burned when heated in air, but were not affected by aqueous acids or aqueous oxidising agents. Thorium phosphide has been made by reducing ThCI4 with phosphorus vapour. 

With the small cations Mg+2 and Mn+2, Dy2S3 does not give any phase with the thorium phosphide structure. Calcium sulfide, on the other hand, yields phases with this structure with Dy2S3 and Y2S3 but not with Er2S3 (maximum value of Ra = 0.94).

There are only two solid thorium phosphides, ThP(cr) and Th3P4(cr), and little thermodynamic information is available on either of these. 

In the absence of any other selected thermodynamic data for the thorium phosphides, no further processing of these results can be attempted.
