Pr2Ni2Sn crystallizes in the orthorhombic Immm space group. Pr(1) is bonded in a 10-coordinate geometry to six equivalent Ni(1) and four equivalent Sn(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to six equivalent Pr(1), one Ni(1), and two equivalent Sn(1) atoms. Sn(1) is bonded to eight equivalent Pr(1) and four equivalent Ni(1) atoms to form a mixture of face and edge-sharing SnPr8Ni4 cuboctahedra.
Pr2Ni2Sn crystallizes in the orthorhombic Immm space group. Pr(1) is bonded in a 10-coordinate geometry to six equivalent Ni(1) and four equivalent Sn(1) atoms. There are four shorter (3.05 Å) and two longer (3.07 Å) Pr(1)-Ni(1) bond lengths. There are two shorter (3.37 Å) and two longer (3.38 Å) Pr(1)-Sn(1) bond lengths. Ni(1) is bonded in a 9-coordinate geometry to six equivalent Pr(1), one Ni(1), and two equivalent Sn(1) atoms. The Ni(1)-Ni(1) bond length is 2.41 Å. Both Ni(1)-Sn(1) bond lengths are 2.75 Å. Sn(1) is bonded to eight equivalent Pr(1) and four equivalent Ni(1) atoms to form a mixture of face and edge-sharing SnPr8Ni4 cuboctahedra.
