Abstract: | Synthesis and Crystal Structure of KMgCu4V3O13 . Single crystals of KMgCu4V3O13 were prepared by supercooled melts. It crystallizes with monoclinic symmetry space group C –P21/m (Nr. 11), unit cell dimensions: a = 10.7144 Å, b = 6.0282 Å, c = 8.3365 Å, β = 98.075°, Z = 2. The crystal structure is closely related to the BaMg2Cu8O6O26 type. Cu2+ occurs in an unusual trigonal bipyramidal coordination. |
