Abstract A novel hybrid network based on octamolybdate building unit, Cu5^1 BBTZ3H2O[β-Mo^V Mo7ⅥO26 ] 1, BBTZ = 1,4-his （ 1,2,4-triazol-1 -ylmethyl ） benzene ], has been synthesized under ionothermal conditions and structurally characterized by single crystal X-ray diffraction. Compound 1 is a rarely self-penetration network constructed by three dimensional（3D） poly-rings networks and （4,4） 2D layers, in which the two interpenetrating parts were united together through Cu2 and Cul centers. Further, the infrared（IR） spectrum, thermogravimetric （TG） analysis and photocatalytic studies were also performed to authenticate the identities of the title compound. Photocatalytic study revealed that compound 1 was active for photocatalytic H2 evolution under UV irradiation.
