Abstract

Ba6Nd3TiCu6(MoO12)2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form distorted BaO12 cuboctahedra that share corners with eight BaO12 cuboctahedra, faces with five BaO12 cuboctahedra, a faceface with one TiO6 octahedra, faces with three equivalent MoO6 octahedra, and faces with four CuO5 square pyramids. There are a spread of Ba–O bond distances ranging from 2.82–3.12 Å.

The corner-sharing octahedral tilt angles are 4°. There are four shorter (1.99 Å) and one longer (2.53 Å) Cu–O bond lengths. In the third Cu+1.83+ site, Cu+1.83+ is bonded to five O2- atoms to form CuO5 square pyramids that share a cornercorner with one MoO6 octahedra, corners with four CuO5 square pyramids, and faces with four BaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 4°. There are four shorter (1.99 Å) and one longer (2.53 Å) Cu–O bond lengths. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a 6-coordinate geometry to two Ba2+, two Nd3+, and two Cu+1.83+ atoms.
