STUDIES ON THE MOLECULAR STRUCTURE OF WT-12 DERIVATIVE OF PYRAZOLO [3,4-d] - 1,3,2-DIAZAPHOSPHORIN-6-ONE

<正> The title compound was obtained by reaction of 1-phenyl-5-benzy-lamino-pyrazole-4-(N-methyl) carboxamide with p-fluorophenyl phosphorus dichloride and its molecular structure determined by X-ray diffraction method. The crystal is mono-clinic,space group P21/c,with a=11. 874(2),b= 12. 986(2),c=14. 587(2) A ,β= 106. 21(1)°,V=2159. 6A3,Mr = 430. 43(C24H20N4OFP),Z=4, Dx = 1. 324g/cm-3,μ(MoKa) = 1. 53cm-1 ,and F(000) = 896. The atoms in the pyrazolo3,4-d] - 1,3,2-di-azaphosphorin-6-one are coplanar except the P atom.
