摘要
将SrCO_(3)与3-硝基-1,2,4-三唑-5-酮(NTO)分散于蒸馏水中,加热搅拌制备出NTO锶溶液,再与碳酰肼(CHZ)水溶液反应合成了新型配合物:{[Sr(CHZ)_(2)(H_(2)O)](NTO)_(2)?.5H_(2)O}_(n)。其化学式为C_(6)H_(23)N_(16)O_(12.5)Sr,Mr=606.97),并对其进行了元素分析和红外表征,利用单晶分析测定了晶体结构。晶体属于单斜晶系,空间群为C2/c,晶体学数据如下:a=24.587(5),b=12.689(2),c=16.481(4)?=121.15(1)埃琕=4400.4(2)?,Z=8,Dc=1.833 g/cm^(3),?=0.255 cm^(-1),F(000)=2472,R=0.0989,wR=0.0750。
The coordination compound of{[Sr(CHZ)_(2)(H_(2)O)](NTO)2?.5H_(2)O}_(n)was prepared by mixing carbohydrazide aqueous solution and strontium salt solution which was obtained through the reaction of strontium carbonate and 3-nitro-1,2,4-triazolo-5-one(NTO).The compound was characterized by using elemental analysis and FT-IR.The crystal structure of{[Sr(CHZ)_(2)(H_(2)O)]?NTO)2?.5H_(2)O}_(n)(C_(6)H_(23)SrN_(16)O_(12.5),Mr=607.02)was determined by using single-crystal diffraction.The crystal is of monoclinic,space group C2/c with the unit cell parameters:a=24.587(5),b=12.689(2),c=16.481(4),?=121.15(1),V=4400.4(2)?,Z=8,Dc=1.833 g/cm^(3),?=0.255cm^(-1),F(000)=2472,R=0.0989 and wR=0.0750.
