The compound described by BaPtSi3 crystallizes in the tetragonal I4mm space group. Ba(1) is bonded in a 17-coordinate geometry to five equivalent Pt(1), four equivalent Si(1), and eight equivalent Si(2) atoms. Pt(1) is bonded in a 5-coordinate geometry to five equivalent Ba(1), one Si(1), and four equivalent Si(2) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a distorted single-bond geometry to four equivalent Ba(1), one Pt(1), and four equivalent Si(2) atoms. In the second Si site, Si(2) is bonded in a 8-coordinate geometry to four equivalent Ba(1), two equivalent Pt(1), and two equivalent Si(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
