C<sub>2</sub>6H<sub>3</sub>1GeO<sub>5</sub>P is monoclinic,space group P2<sub>1</sub>/c,a=14.287(4),b=8.045(2),c=23.381(6),β=103.79(2)°,V=2622.7,Mr=527.10,Z=4,Dx=1.34g/cm3,μ=12.4cm.F(000)=1096.The final R=0.051 and R<sub>w</sub>=0.057 for 2446 observed unique reflections[I≥3σ(I).The results indicated that all non-hydrogen atoms between phosphorus and germanium in the title compound were located almost in coplane with farthest deviation of atom Ge defined by 0. 3657.The values of Ge-C(phenyl) and Ge-C(alkyl) bond distance are 1.938(5),1.945(5) and 1.976(5),respectively. 展开更多
