| Struktur von C2C16N4P2, dem R eaktionsprodukt von D icyandiam id mit PC15 Structure of C 2C16N4P2, the Reaction Product of Dicyandiamide with PC15  | | | | Abstract
| The reaction product of dicyanodiamide with PC15 (1:2) is 2,2,4-trichloro-2,2-dihydro-6-trichlorophosphazeno-1.3,5,2A5-triazaphosphorine and not 2.4,6-trichloro-2,2-dihydro-2-trichlorophosphazeno-l,3,5,2A5-triazaphosphorine as reported in the literature. This is con firmed by an X-ray structure determination at 90K: Space group P 2,/c, a = 17.258(5), b = 9.664(3), c = 15.070(4) Ä, ß = 114.05(2)°, Z = 8, R = 3.99%. Both molecules of the asymmetric unit show about the same conformation with approximate C s-m -symmetry as was also obtai ned by semi-empirical MNDO calculations. The thermal motion analysis establishes that the molecules cannot be described as 'rigid bodies', and that the easy deformability of the exocyclic C-N-P angles allows the 'rigid' NPC13 tetrahedra to perform almost isotropic librations. | | | |
