Cu(en)_2Ag(SCN)_3 crystallizes in space group P2_12_12_1 with its cell parameters, a=7.126(2), b=12.587(5), c=17.585(5). There are four formula units per unit cell(ρ_obs.=1.90g/cm~3, ρ_(calc.=1.96g/cm~3). Diffraction data are collected on a CAD4 four-circle diffractometer using Mo-Ka radiation. The structure is determiued by heavy atom method, then refined by leastsquare method to a final R=0.036. It is shown that in the crystal the coordination of Cu atoms is square pyramidal with four N atoms of en groups in the square plane and oue Natom of thiocyanate group in the apical position. The Ag atom is coordinated tetrahedrally by four S atoms of thiocyanate groups, one of which links up two AgS_4 together, thus forming the infinite AgS_4 tetrahedron chains along a axis.
