| Abstract: | The gadolinium
complex with triethylenetetraaminehexaacetic acid (abbreviated as H\-6ttha), (NH\-4)\-2\{\
\}\56H\-2O was synthesized in aqueous solution, and its crystal structure was determined by
X\|ray four\|cycle diffraction method. The crystal is monoclinic, space group P21/c, with a=1.040
0(4) nm, b=1.276 1(4) nm, c=2.313 2(4) nm, \{=\}90\^89(3), V=3.070(2) nm3, Z=4, Dc=1.709
g/cm\+3. The complex was a mononuclear molecule, each gadolinium ion is coordinated by four
nitrogen atoms and five carboxyl oxygen atoms from one Httha, forming a coordination
polyhedron of mono capped square antiprism. |
