High Temperature Form

Two modifications of ThNi2P2 were prepared in a tin flux at 850 °C (α-ThNi2P2) and 1000 °C (β-ThNi2P2). The crystal structures of both modifications were refined from single­crystal X-ray data. α-ThNi2P2 (BaCu2S2 type structure): Pnma. a = 819.69(5), b = 394.28(3), c = 981.54(7) pm. R = 0.028 for 32 variables and 654 structure factors: β-ThNi2P2 (CaBe2Ge2 type structure): P4/nmm, a = 408.5(1), c = 908.0(3) pm, R = 0.033 for 15 variable parameters and 261 F values. Although the two structures are closely related, they can be transformed into each other only by a reconstructive phase transformation. The differences and similari­ties of the two structures are discussed. The high temperature form has higher symmetry, a smaller number of variable positional parameters, and a tendency for higher coordination numbers.

Molecular Volume

Large variations of the molecular volume of the monochalcogenides of rare earths are attributed to cation-cation bond which involves one deep valence electron. Similar results are found with monochalgenides of 3d metals. The phase transformation Ceγ ⇄ Ceα is interpreted in a similar way bearing in mind the existence of compounds such as XeF4. This work introduces the notion of reliance which enlightens the notion of valence and is closely related, to the notion of intermediate and fluctuating valences.

Solid Phase Transition

In the temperature range of 280 to 350 K, there is a solid-to-solid phase transition for each complex, which is further evidenced by four thermal circulating processes with the scanning rate of 10 K min−1.
