Abstract
Pb5GeO4(VO4)2 crystallizes in the monoclinic Pm space group. The structure is three-dimensional. there are four inequivalent V5+ sites. In the first V5+ site, V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share corners with three PbO6 pentagonal pyramids and an edgeedge with one PbO6 pentagonal pyramid. There are a spread of V–O bond distances ranging from 1.73–1.77 Å. In the second V5+ site, V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share corners with two PbO6 pentagonal pyramids and an edgeedge with one PbO6 pentagonal pyramid. There are a spread of V–O bond distances ranging from 1.72–1.77 Å. In the third V5+ site, V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share corners with four PbO6 pentagonal pyramids and an edgeedge with one PbO6 pentagonal pyramid. There are a spread of V–O bond distances ranging from 1.73–1.77 Å. In the fourth V5+ site, V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share corners with four PbO6 pentagonal pyramids and an edgeedge with one PbO6 pentagonal pyramid. There are a spread of V–O bond distances ranging from 1.73–1.77 Å. There are eight inequivalent Pb2+ sites.more »
