Abstract

Nd(CO3)2CO2O2 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of four carbon dioxide molecules; four hydrogen peroxide molecules; and one Nd(CO3)2 sheet oriented in the (0, 0, 1) direction. In the Nd(CO3)2 sheet, Nd is bonded in a 6-coordinate geometry to six O atoms. There are a spread of Nd–O bond distances ranging from 2.27–2.46 Å. There are two inequivalent C sites. In the first C site, C is bonded in a distorted bent 120 degrees geometry to two O atoms. There is one shorter (1.26 Å) and one longer (1.27 Å) C–O bond length. In the second C site, C is bonded in a trigonal planar geometry to three O atoms. There is two shorter (1.25 Å) and one longer (1.41 Å) C–O bond length. There are six inequivalent O sites. In the first O site, O is bonded in a distorted bent 120 degrees geometry to one Nd and one C atom. In the second O site, O is bonded in a distorted bent 150 degrees geometry to one Nd and one C atom. In the third O site, O is bonded in a bent 150 degrees geometry to one Nd and one C atom. In the fourth O site, O is bonded in a 2-coordinate geometry to one Nd and one O atom. The O–O bond length is 1.48 Å. In the fifth O site, O is bonded in a distorted single-bond geometry to one Nd, one C, and one O atom. In the sixth O site, O is bonded in a bent 120 degrees geometry to one Nd and one C atom.
