Synthesis and crystal structure of Keggin compound [(CH2)5NH2]3[PMo12O40]
【摘要】 以钼磷酸和哌啶(PPD)为原料,在乙腈和水的混合溶剂中,制备了多金属氧酸盐化合物得[(CH2)5NH2]3[PMo12O40],并测定了化合物的晶体结构.结果表明:晶体属三斜晶系,空间群,结晶学参数a=1.3543(3)nm,b=1.8385(3)nm,c=1.9494(4)nm,β=P-89.85(10)°,V=1.7428(6)nm3,Z=1,Dc=2.563mg/cm3,F(000)=3334,R1=0.0695,wR2=0.1438.该化合物分子是由1个杂多阴离子和4个质子化的哌啶分子组成.
【Abstract】 A charge transfer complex,[(CH2)5NH2]3[PMo12O40],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) nm3,Z=1,Dc=2.563 (mg/cm3),F(000)=3 334,R1=0.069 5,wR2=0.143 8.The crystal structure indicates that three piperidines act as the counter cations which combines to the [PMo12O40]3-anion.
