PrCoGe2 crystallizes in the orthorhombic Cmcm space group. Pr(1) is bonded in a 14-coordinate geometry to four equivalent Co(1), four equivalent Ge(2), and six equivalent Ge(1) atoms. Co(1) is bonded in a 5-coordinate geometry to four equivalent Pr(1), one Ge(1), and four equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to six equivalent Pr(1), one Co(1), and two equivalent Ge(1) atoms. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to four equivalent Pr(1) and four equivalent Co(1) atoms.
PrCoGe2 crystallizes in the orthorhombic Cmcm space group. Pr(1) is bonded in a 14-coordinate geometry to four equivalent Co(1), four equivalent Ge(2), and six equivalent Ge(1) atoms. All Pr(1)-Co(1) bond lengths are 3.24 Å. There are two shorter (3.15 Å) and two longer (3.17 Å) Pr(1)-Ge(2) bond lengths. There are four shorter (3.18 Å) and two longer (3.34 Å) Pr(1)-Ge(1) bond lengths. Co(1) is bonded in a 5-coordinate geometry to four equivalent Pr(1), one Ge(1), and four equivalent Ge(2) atoms. The Co(1)-Ge(1) bond length is 2.28 Å. There are two shorter (2.38 Å) and two longer (2.41 Å) Co(1)-Ge(2) bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to six equivalent Pr(1), one Co(1), and two equivalent Ge(1) atoms. Both Ge(1)-Ge(1) bond lengths are 2.60 Å. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to four equivalent Pr(1) and four equivalent Co(1) atoms.
