Nd4Co3Ge8 crystallizes in the orthorhombic Pmm2 space group. The structure is three-dimensional. there are four inequivalent Nd sites. In the first Nd site, Nd is bonded in a 10-coordinate geometry to four equivalent Co and ten Ge atoms. All Nd–Co bond lengths are 3.29 Å. There are a spread of Nd–Ge bond distances ranging from 3.14–3.27 Å. In the second Nd site, Nd is bonded in a 4-coordinate geometry to four equivalent Co and ten Ge atoms. All Nd–Co bond lengths are 3.25 Å. There are a spread of Nd–Ge bond distances ranging from 3.16–3.35 Å. In the third Nd site, Nd is bonded in a 10-coordinate geometry to ten Ge atoms. There are a spread of Nd–Ge bond distances ranging from 3.12–3.34 Å. In the fourth Nd site, Nd is bonded in a 4-coordinate geometry to four equivalent Co and ten Ge atoms. All Nd–Co bond lengths are 3.24 Å. There are a spread of Nd–Ge bond distances ranging from 3.16–3.32 Å. There are three inequivalent Co sites. In the first Co site, Co is bonded in a 5-coordinate geometry to four equivalent Nd and five Ge atoms. There are a spread of Co–Ge bond distances ranging from 2.28–2.40 Å. In the second Co site, Co is bonded in a 5-coordinate geometry to four equivalent Nd and five Ge atoms. There are a spread of Co–Ge bond distances ranging from 2.33–2.39 Å.
