BaPtIn3 crystallizes in the tetragonal I4mm space group. Ba(1) is bonded in a 16-coordinate geometry to four equivalent Pt(1), four equivalent In(2), and eight equivalent In(1) atoms. Pt(1) is bonded in a 5-coordinate geometry to four equivalent Ba(1), one In(2), and four equivalent In(1) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded in a distorted bent 120 degrees geometry to four equivalent Ba(1) and two equivalent Pt(1) atoms. In the second In site, In(2) is bonded in a distorted single-bond geometry to four equivalent Ba(1) and one Pt(1) atom.
BaPtIn3 crystallizes in the tetragonal I4mm space group. Ba(1) is bonded in a 16-coordinate geometry to four equivalent Pt(1), four equivalent In(2), and eight equivalent In(1) atoms. All Ba(1)-Pt(1) bond lengths are 3.73 Å. All Ba(1)-In(2) bond lengths are 3.60 Å. There are four shorter (3.71 Å) and four longer (3.88 Å) Ba(1)-In(1) bond lengths. Pt(1) is bonded in a 5-coordinate geometry to four equivalent Ba(1), one In(2), and four equivalent In(1) atoms. The Pt(1)-In(2) bond length is 2.68 Å. All Pt(1)-In(1) bond lengths are 2.73 Å. There are two inequivalent In sites. In the first In site, In(1) is bonded in a distorted bent 120 degrees geometry to four equivalent Ba(1) and two equivalent Pt(1) atoms.
