A new two-dimensional (2D) oxosulfide, (N2H4)(2)Mn3Sb4S8((3)-OH)(2) (1), has been successfully synthesized under surfactant-thermal conditions with hexadecyltributylphosphonium bromide as the surfactant. Compound1 has a layered structure and contains a novel [Mn-3((3)-OH)(2)](n) chain along the b-axis. The photocatalytic activity for compound1 has been demonstrated under visible-light irradiation and continuous H-2 evolution was observed. Our results indicate that surfactant-thermal synthesis could be a promising method for growing novel crystalline oxochalcogenides with interesting structures and properties.
