Co Pb W W W
W3CoPb is (Cubic) Perovskite structured and crystallizes in the trigonal R3m space group. W(1) is bonded in a 5-coordinate geometry to four equivalent Co(1) and two equivalent Pb(1) atoms. There are a spread of W(1)-Co(1) bond distances ranging from 3.27-3.71 Å. There is one shorter (2.31 Å) and one longer (2.62 Å) W(1)-Pb(1) bond length. Co(1) is bonded to twelve equivalent W(1) atoms to form distorted CoW12 cuboctahedra that share corners with twelve equivalent Co(1)W12 cuboctahedra, faces with six equivalent Co(1)W12 cuboctahedra, and faces with eight equivalent Pb(1)W6 octahedra. Pb(1) is bonded to six equivalent W(1) atoms to form PbW6 octahedra that share corners with six equivalent Pb(1)W6 octahedra and faces with eight equivalent Co(1)W12 cuboctahedra. The corner-sharing octahedra are not tilted.
