| oxo-lA 5 ,3A 5 -diphosphaz-2-en, (NH2)2 (0)P-N=P(NH2)3 Synthesis, Crystal Structure, and Properties of 1,1,3,3,3-Pentaam ino-l-oxo-l A 5 , 3 A 5 -diphosphaz-2-ene, (NH2)2(0)P-N =P(N H i)3 Coarse crystalline (NH2)2(0)P-N=P(NH2)3 is obtained from a NH;* saturated CH2C12 suspen sion of (NH2)2(0)P-N=P(NH2)3 NH4C1 at room temperature. (NH2)2(0)P-N=P(NH2)3 NH4C1 is synthesized" by slow addition of C12(0)P-N=PC13 to a solution of NH3 in CH2C12 at -78 °C. Excess NH4C1 is removed by treatment with HNEt2 followed by extraction with CH2C12. The crystal structure of (NH2)2(0)P-N=P(NH2)3 has been determined by single crystal X-ray methods (P2(/c; a = 1462.8(3), b = 944.8(2), c = 1026.9(2) pm, /3 = 110.69(3)°; Z = 8). In the unit cell there are two crystallographically unique molecules. They form a three dimensional network by intermolecular hydrogen bonding interactions (N-H- • N > 313 pm. N-H • 0 > 293 pm). The investigation of the thermal properties shows decomposition with evolution of NH3 above 80 °C. | | | |
