Pr2Ni2Ga crystallizes in the orthorhombic Immm space group. Pr(1) is bonded in a 10-coordinate geometry to six equivalent Ni(1) and four equivalent Ga(1) atoms. Ni(1) is bonded in a 10-coordinate geometry to six equivalent Pr(1), two equivalent Ni(1), and two equivalent Ga(1) atoms. Ga(1) is bonded to eight equivalent Pr(1) and four equivalent Ni(1) atoms to form a mixture of distorted face and edge-sharing GaPr8Ni4 cuboctahedra.
Pr2Ni2Ga crystallizes in the orthorhombic Immm space group. Pr(1) is bonded in a 10-coordinate geometry to six equivalent Ni(1) and four equivalent Ga(1) atoms. There are two shorter (2.95 Å) and four longer (3.04 Å) Pr(1)-Ni(1) bond lengths. There are two shorter (3.21 Å) and two longer (3.36 Å) Pr(1)-Ga(1) bond lengths. Ni(1) is bonded in a 10-coordinate geometry to six equivalent Pr(1), two equivalent Ni(1), and two equivalent Ga(1) atoms. There is one shorter (2.60 Å) and one longer (2.82 Å) Ni(1)-Ni(1) bond length. Both Ni(1)-Ga(1) bond lengths are 2.56 Å. Ga(1) is bonded to eight equivalent Pr(1) and four equivalent Ni(1) atoms to form a mixture of distorted face and edge-sharing GaPr8Ni4 cuboctahedra.
