An X-ray crystal structure analysis was carried out for 1. | | | |

| Phosphonio-substituierte Tetrahydro-l,3-diphosphinine un(j Tetrahy dro-1,2,6-azad i phospli in i ne | | | | Abstract
| The bis(triphenylphosphonio)propenide cation 1 provides two reactive CH sites in 1,3-position and can be condensed with the bis(dichlorophosphanyl)methylene triphenylphos-phorane 2 or the bis(dichlorophosphanyl)aniline 3 to form cationic six-membered rings: A tetrahydro-1,3-diphosphinine (4) with three phosphonio or phosphoranediyl substituents in 2,4,6-position and a tetrahydro-1,2,6-azadiphosphinine (5) carrying two such substituents in 3,5-position. The bromide of the latter was used for an X-ray structure analysis. The P111 ring members of the cations 4 and 5 can be oxidized in two steps by elemental sulfur to give the monothioxo and dithioxo derivatives 6. 7 and 8, 9. respectively. A crystal of the mixed chloride/bromide of 8 was used for another X-ray structure analysis. | | | |

| 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. | | | |
