ReSi2 is Protactinium-derived structured and crystallizes in the tetragonal I4/mmm space group. Re(1) is bonded in a distorted q6 geometry to ten equivalent Si(1) atoms. Si(1) is bonded in a distorted q6 geometry to five equivalent Re(1) and five equivalent Si(1) atoms.
ReSi2 is Protactinium-derived structured and crystallizes in the tetragonal I4/mmm space group. Re(1) is bonded in a distorted q6 geometry to ten equivalent Si(1) atoms. There are two shorter (2.61 Å) and eight longer (2.62 Å) Re(1)-Si(1) bond lengths. Si(1) is bonded in a distorted q6 geometry to five equivalent Re(1) and five equivalent Si(1) atoms. There are four shorter (2.60 Å) and one longer (2.65 Å) Si(1)-Si(1) bond length.
