Single crystals of the new compound, NaMn 2 V 3 O 10 , were grown by conventional solid-state reaction. The crystal structure of the synthesized sample was determined using single-crystal X-ray diffraction data. NaMn 2 V 3 O 10 crystallizes in the triclinic system with space group P 1 - and cell parameters a  = 6.854 (2) Å, b  = 6.877 (2) Å, c  = 9.716 (2) Å, α  = 100.604 (1)°, β  = 104.169 (1)°, and γ  = 101.390 (1)°. The structure of this vanadate built up from the connection of V 3 O 10 groups and MnO 6 octahedra via corners leading to an open three-dimensional framework delimiting tunnels along [001] direction, where the Na + cations are localized. The powder of NaMn 2 V 3 O 10 was prepared by Pechini method. The magnetic measurement has been evidenced by Curie–Weiss behavior above 4.5 K with θ  = − 25.46 K demonstrating the occurrence of predominant antiferromagnetic interactions between Mn 2+ cations.
