The crystal structure of the [Dy(NО_3)_2(HMPA)_4](NО_3) complex (HMPA is hexamethylphosphorotriamide) is studied by X-ray diffraction analysis. The crystals are constructed of two crystallographically independent complex cations [Dy(NО_3)_2(HMPA)_4]^+ and outer-sphere [NO_3]^−1 groups. The structure is represented by separate С_24Н_72DyN_15O_13P_4 complexes bound by van der Waals interactions with pronounced layered morphology. The coordination polyhedron of Dy(III) with coordination number 8 is represented by a distorted trigonal prism with two centered square faces. The results of investigation of the luminescent properties in the visible and near-IR regions are presented.
