Ca14Hg51 is beta Plutonium-derived structured and crystallizes in the hexagonal P-6 space group. The structure is three-dimensional. there are five inequivalent Ca sites. In the first Ca site, Ca is bonded in a 12-coordinate geometry to fourteen Hg atoms. There are a spread of Ca–Hg bond distances ranging from 3.27–3.77 Å. In the second Ca site, Ca is bonded in a 8-coordinate geometry to fourteen Hg atoms. There are a spread of Ca–Hg bond distances ranging from 3.27–3.72 Å. In the third Ca site, Ca is bonded in a 2-coordinate geometry to thirteen Hg atoms. There are a spread of Ca–Hg bond distances ranging from 3.32–3.57 Å. In the fourth Ca site, Ca is bonded in a 1-coordinate geometry to fourteen Hg atoms. There are a spread of Ca–Hg bond distances ranging from 3.19–3.61 Å. In the fifth Ca site, Ca is bonded in a 6-coordinate geometry to fifteen Hg atoms. There are a spread of Ca–Hg bond distances ranging from 3.37–3.59 Å. There are thirteen inequivalent Hg sites. In the first Hg site, Hg is bonded in a 3-coordinate geometry to three equivalent Ca and eight Hg atoms. There are six shorter (3.14 Å) and two longer (3.28 Å) Hg–Hg bond lengths. In the second Hg site, Hg is bonded in a 3-coordinate geometry to three equivalent Ca and eight Hg atoms. There are six shorter (3.14 Å) and two longer (3.25 Å) Hg–Hg bond lengths. In the third Hg site, Hg is bonded in a 11-coordinate geometry to four Ca and five Hg atoms. There are a spread of Hg–Hg bond distances ranging from 3.07–3.37 Å. In the fourth Hg site, Hg is bonded in a 4-coordinate geometry to four Ca and five Hg atoms. There are a spread of Hg–Hg bond distances ranging from 3.09–3.35 Å. In the fifth Hg site, Hg is bonded in a 3-coordinate geometry to three equivalent Ca and seven Hg atoms. All Hg–Hg bond lengths are 3.29 Å. In the sixth Hg site, Hg is bonded in a 11-coordinate geometry to four Ca and seven Hg atoms. There are two shorter (3.00 Å) and one longer (3.25 Å) Hg–Hg bond lengths. In the seventh Hg site, Hg is bonded in a 2-coordinate geometry to four Ca and eight Hg atoms. There are a spread of Hg–Hg bond distances ranging from 2.99–3.32 Å. In the eighth Hg site, Hg is bonded in a 11-coordinate geometry to four Ca and seven Hg atoms. There are one shorter (2.99 Å) and one longer (3.27 Å) Hg–Hg bond lengths. In the ninth Hg site, Hg is bonded in a 3-coordinate geometry to four Ca and six Hg atoms. There are a spread of Hg–Hg bond distances ranging from 3.14–3.28 Å. In the tenth Hg site, Hg is bonded to four Ca and eight Hg atoms to form a mixture of distorted edge and face-sharing HgCa4Hg8 cuboctahedra. There are one shorter (2.92 Å) and one longer (2.93 Å) Hg–Hg bond lengths. In the eleventh Hg site, Hg is bonded in a 3-coordinate geometry to three equivalent Ca and seven Hg atoms. In the twelfth Hg site, Hg is bonded to four Ca and eight Hg atoms to form a mixture of distorted edge and face-sharing HgCa4Hg8 cuboctahedra. In the thirteenth Hg site, Hg is bonded in a 1-coordinate geometry to three Ca and six Hg atoms. Both Hg–Hg bond lengths are 2.95 Å.
