glycolate)2] results in the formation of a neutral technetium(V) complex [TcOL]. The X-ray structure of this complex confirms a five-coordinate, square based pyramidal geometry with no crystallographic axes of symmetry. Crystal data: orthorhombic space group P212121; a=11.701(1), b=14.949(2), c=7.516(1) A, V=1314.6 A3 to give Z=4 for D=1.68 g cm−3. Structure resolution and refinement based on 2115 reflections
N- [2(1H-吡咯基甲基)]-N′-(4-戊烯-3-一-2)乙烷-1、2-二胺的合成已经完成,该化合物通过X射线衍射表征。C12H19N3O的晶体数据:空间群P21 / c:a = 10.358(3),b = 7.953(1),c = 15.640(4)A,β= 101.63(1)°,V = 1261(2)A3得到对于D = 1.165g cm-3,Z = 4。基于2114个反射的结构求解和优化收敛于R = 0.064,Rw = 0.079。该分子与Bu4N [TcO(乙二醇酸酯)2]的反应导致形成中性tech(V)络合物[TcOL]。该复合物的X射线结构证实了五坐标,基于正方形的金字塔几何形状,没有对称的结晶学轴。晶体数据:正交空间群P212121;a = 11.701(1),b = 14.949(2),c = 7.516(1)A,V = 1314.6 A3,得出D = 1.68 g
