GdCI s. 6 He() is monoclinic with space group P2/n anti two molecules in the cell a=9"651, b=6-525, c=7.923A; fl=93"65 °.All atomic positions (except for hydrogen) were determined with high precision.The structure contains complexes Cl.~(Id(()H.,)6] which are heht togother by ()--H • • • C1 bonds.Thus one third of the chlorine atoms are not bonded to gadolinium atoms.The only symmetry element of a complex is a twofoht axis.The bond lengths are:(l(t-Ci =2.768, Gd-O =2.39-2.42,O-H-.. C1=3.14-3.24:~.
