Abstract
A new Cd-containing transition metal Zintl phase, Sr11Cd 6Sb12, was obtained from a direct element combination reaction using the Sn flux method. Its structure was determined using single-crystal X-ray diffraction methods. It crystallizes in the monoclinic space group C2/m with a=32.903(3)Å, b=4.7666(5)Å, c=12.6057(13)Å, β=109.752(2)°, and Z=2. Sr11Cd 6Sb12 has a one-dimensional infinite chain structure consisting of double pentagonal tubes, where Sr2+ cations reside both within two tubes and between the infinite chains of tubes. The anionic framework [Cd6Sb12]22- has features similar to those of Eu10Mn6Sb13. The difference in Eu 10Mn6Sb13 is that its double pentagonal tubes are further condensed to form two-dimensional layers.
