Abstract

A charge transfer complex,[(CH_2)_5NH_2]_3[PMo_(12)O_(40)],has been synthesized and characterized. The crystal structure of the complex obtained in mixed solvent of acetonit rile and water has been determined by single crystal X-ray diffractometry.It is triclinic lattice,P_(|-)space group,with a=1.354 3(3) nm,b=1.838 5(3) nm,c=1.949 4(4) nm,β=89.85(0)°,V=1.742 8(6) nm~3,Z=1,D_c=2.563 (mg/cm~3),F(000)=3 334,R_1=0.069 5,wR_2=0.143 8.The crystal structure indicates that three piperidines act as the counter cations which combines to the [PMo_(12)O_(40)]~(3-)anion.
