Abstract

CaCd2(O2Cl3)2O2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional and consists of two hydrogen peroxide molecules and one CaCd2(O2Cl3)2 framework. In the CaCd2(O2Cl3)2 framework, Ca is bonded in a 7-coordinate geometry to four O and three Cl atoms. There are a spread of Ca–O bond distances ranging from 2.61–2.77 Å. There are a spread of Ca–Cl bond distances ranging from 2.57–2.71 Å. There are two inequivalent Cd sites. In the first Cd site, Cd is bonded to six Cl atoms to form edge-sharing CdCl6 octahedra. There are a spread of Cd–Cl bond distances ranging from 2.54–2.97 Å. In the second Cd site, Cd is bonded to six Cl atoms to form edge-sharing CdCl6 octahedra. There are a spread of Cd–Cl bond distances ranging from 2.59–2.85 Å. There are four inequivalent O sites. In the first O site, O is bonded in a distorted L-shaped geometry to one Ca and one O atom. The O–O bond length is 1.25 Å. In the second O site, O is bonded in an L-shaped geometry to one Ca and one O atom. The O–O bond length is 1.25 Å. In the third O site, O is bonded in a distorted L-shaped geometry to one Ca and one O atom. In the fourth O site, O is bonded in a 1-coordinate geometry to one Ca and one O atom. There are six inequivalent Cl sites. In the first Cl site, Cl is bonded in a distorted bent 120 degrees geometry to one Ca and one Cd atom. In the second Cl site, Cl is bonded in a distorted bent 150 degrees geometry to one Ca and one Cd atom. In the third Cl site, Cl is bonded in a distorted T-shaped geometry to three Cd atoms. In the fourth Cl site, Cl is bonded in a distorted trigonal non-coplanar geometry to three Cd atoms. In the fifth Cl site, Cl is bonded in a water-like geometry to two Cd atoms. In the sixth Cl site, Cl is bonded in a distorted trigonal planar geometry to one Ca and two Cd atoms.
