A new oxohalogenide compound Ba7CoV6O21Cl4 was synthesized by a conven- tional high-temperature solid state reaction. The title compound is found to crystallize in the orthorhombic system of space group Cmcm with a = 16.726(4), b = 10.568(3), c = 14.808(4) Å, V = 2617.4(12) Å3, Z = 2, Mr = 1803.68, Dc = 3.411 g/cm3, = 11.396 mm-1, F(000) = 3172, the final R = 0.0314 and wR = 0.0750 for 1531 observed reflections with I > 2(I). Co2+ ions are coordinated by four O and two Cl atoms, forming a CoO4Cl2 octahedron, while V atoms are tetrahedrally coordinated, forming (V2O7)4- groups. The structure of Ba7CoV6O21Cl4 exhibits a pseudo-one- dimensional chain running along the c-axis. Magnetic measurements confirm that Ba7CoV6O21Cl4 shows a paramagnetic behavior down to 2 K.
