La2Ni12P5 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are two inequivalent La sites. In the first La site, La is bonded in a 7-coordinate geometry to seven P atoms. There are a spread of La–P bond distances ranging from 3.08–3.15 Å. In the second La site, La is bonded in a 8-coordinate geometry to fourteen Ni and four P atoms. There are a spread of La–Ni bond distances ranging from 2.99–3.50 Å. There are two shorter (3.01 Å) and two longer (3.03 Å) La–P bond lengths. There are twelve inequivalent Ni sites. In the first Ni site, Ni is bonded in a distorted water-like geometry to two equivalent P atoms. Both Ni–P bond lengths are 2.32 Å.
