| Abstract: | The crystal and molecular structure of C5H4C(CH3)2CH2CH=CH2Sm(OH)Cl2MgCl24THF is reported. It is triclinic. The crystallographic data are as follows: space group P1 , a=10.773(2), b=12.836(3), c=15.478(3) , =111.46(3), =107.71(3), =92.54(3), V=1868(1) 3, Mr=827.91, Dx=1.472 g/cm3, =2.0006 mm1, F(000)=840, Z=2, R=0.041, wR=0.050 (I3(I)). In this molecule the coordination number of Sm() atoms is 8 and the coordination geometry of Sm() is a seriously distorted octahedron. The coordinations of Mg(1) and Mg(2) are similar, their coordination numbers are all 6 and their coordiantion geometries are all distorted octahedra. The three octahedra are linked up by three coplanes. |
