Synthesis and crystal structure of Ca(VO) 2(PO 4) 2
A new phosphate, Ca(VO) 2(PO 4) 2, was synthesized hydrothermally and its structure was determined from single-crystal X-ray diffraction data. It crystallizes in the noncentrosymmetric orthorhombic space group Fdd2 with a = 11.795(4), b = 15.784(6), c = 7.190(4)Å, Z = 8, and R = 0.0346. The structur...

Summary: | A new phosphate, Ca(VO)
2(PO
4)
2, was synthesized hydrothermally and its structure was determined from single-crystal X-ray diffraction data. It crystallizes in the noncentrosymmetric orthorhombic space group
Fdd2 with
a = 11.795(4),
b = 15.784(6),
c = 7.190(4)Å,
Z = 8, and
R = 0.0346. The structure consists of infinite chains of
trans-corner-sharing VO
6 octahedra cross-linked by phosphate groups to form a 3-dimensional network. These chains have alternating short and long V
O bonds. The network contains intersecting channels where the Ca
2+ cations are located. The structure is compared with those of the
AVOPO
4 (A =alkali metal) family. |
