A new mixed valent chromium-layered oxide, Sr 4.5 Cr 2.5 O 9 , with a structure closely related to the 990201+1201:: structure of the superconducting cuprate TlBa 2Ψx La 2Ψx Cu 2 O 9 , has been synthesized at normal pressure. This orthorhombic phase (a β«Ψβ¬ 10.7959(2) A > , b β«Ψβ¬ 5.4012(1) A > , and
