The structure described by CaCaTb2Eu2V2O12 crystallizes in the orthorhombic P222 space group. The structure consists of two 7440-70-2 atoms inside a CaTb2Eu2V2O12 framework. In the CaTb2Eu2V2O12 framework, there are two inequivalent Ca sites. In the first Ca site, Ca(3) is bonded in a square co-planar geometry to four equivalent O(2) atoms. In the second Ca site, Ca(4) is bonded in a square co-planar geometry to four equivalent O(1) atoms. Tb(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form TbO6 octahedra that share corners with six equivalent V(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 22-26°. There are four inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a distorted square co-planar geometry to four equivalent O(1) and four equivalent O(5) atoms. In the second Eu site, Eu(2) is bonded in a rectangular see-saw-like geometry to four equivalent O(6) atoms. In the third Eu site, Eu(3) is bonded in a distorted square co-planar geometry to four equivalent O(4) atoms. In the fourth Eu site, Eu(4) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(3) atoms. V(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form VO6 octahedra that share corners with six equivalent Tb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 22-26°. There are six inequivalent O sites. In the first O site, O(5) is bonded in a 3-coordinate geometry to one Tb(1), one Eu(1), and one V(1) atom. In the second O site, O(6) is bonded in a 3-coordinate geometry to one Tb(1), one Eu(2), and one V(1) atom. In the third O site, O(1) is bonded in a 3-coordinate geometry to one Ca(4), one Tb(1), one Eu(1), and one V(1) atom. In the fourth O site, O(2) is bonded in a 3-coordinate geometry to one Ca(3), one Tb(1), and one V(1) atom. In the fifth O site, O(3) is bonded in a 3-coordinate geometry to one Tb(1), one Eu(4), and one V(1) atom. In the sixth O site, O(4) is bonded in a 3-coordinate geometry to one Tb(1), one Eu(3), and one V(1) atom. is represented by the CIF file [CIF]
