Résumé :

The atomization energies of the molecule CP, previously identified and of C2P, CP2 and C2P2. characterized here, were determined: D0o(CP) = 509.6 ± 8 or 121.8 ± 2; ΔH0o, at (C2P) = 1124 ± 15 or 268.7 ± 3.5; ΔH0o, at (CP2) = 980 ± 15 or 234.3 ± 3.5 and ΔH0o, at (C2P2) = 1642 ± 15 or 392.5 ± 3.5 kJ mole-1 or kcal mole-1, respectively. The comparison of the measured atomization energies with the bond strengths suggests that C2P has the structure CCP, but that CP2 may be a mixture of both the isomers PCP and CPP. © 1971.
