Materials Data on Cd4NiH20(ClO)10 by Materials Project
NiCd4H16(O4Cl5)2(H2O)2 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of four water molecules and two NiCd4H16(O4Cl5)2 sheets oriented in the (0, 1, 0) direction. In each NiCd4H16(O4Cl5)2 sheet, Ni2+ is bonded in an octahedral geometry to six O2- atoms. There are four shorter (2.07 Å) and two longer (2.11 Å) Ni–O bond lengths. There are two inequivalent Cd2+ sites. In the first Cd2+ site, Cd2+ is bonded to six Cl1- atoms to form edge-sharing CdCl6 octahedra. There are a spread of Cd–Cl bond distances ranging from 2.58–2.71 Å. In the second Cd2+ site, Cd2+ is bonded to one O2- and five Cl1- atoms to form edge-sharing CdCl5O octahedra. The Cd–O bond length is 2.41 Å. There are a spread of Cd–Cl bond distances ranging from 2.60–2.83 Å. There are eight inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one O2- and one Cl1- atom. The H–O bond length is 0.99 Å. The H–Cl bond length is 2.11 Å. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to one Cd2+ and two H1+ atoms. In the second O2- site, O2- is bonded in a distorted water-like geometry to one Ni2+ and two H1+ atoms. In the third O2- site, O2- is bonded in a distorted water-like geometry to one Ni2+ and two H1+ atoms. In the fourth O2- site, O2- is bonded in a distorted water-like geometry to one Ni2+ and two H1+ atoms. There are five inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a distorted water-like geometry to one Cd2+ and one H1+ atom. In the second Cl1- site, Cl1- is bonded in a distorted T-shaped geometry to three Cd2+ atoms. In the third Cl1- site, Cl1- is bonded in a 3-coordinate geometry to three Cd2+ atoms. In the fourth Cl1- site, Cl1- is bonded in a water-like geometry to two Cd2+ atoms. In the fifth Cl1- site, Cl1- is bonded in an L-shaped geometry to two Cd2+ atoms.
