Abstract

Pb4AsH(OCl)4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are four inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded in a 1-coordinate geometry to one O2- and six Cl1- atoms. The Pb–O bond length is 2.39 Å. There are a spread of Pb–Cl bond distances ranging from 2.87–3.62 Å. In the second Pb2+ site, Pb2+ is bonded in a 5-coordinate geometry to three O2- and three Cl1- atoms. There are a spread of Pb–O bond distances ranging from 2.37–2.58 Å. There are a spread of Pb–Cl bond distances ranging from 2.95–3.53 Å. In the third Pb2+ site, Pb2+ is bonded in a 8-coordinate geometry to four O2- and four Cl1- atoms. There are a spread of Pb–O bond distances ranging from 2.48–2.67 Å. There are a spread of Pb–Cl bond distances ranging from 3.20–3.40 Å. In the fourth Pb2+ site, Pb2+ is bonded in a 6-coordinate geometry to three O2- and three Cl1- atoms. There are a spread of Pb–O bond distances ranging from 2.33–2.49 Å. There are a spread of Pb–Cl bond distances ranging from 2.98–3.50 Å. As3+ is bonded in a distorted T-shaped geometry to three O2- atoms. There are a spread of As–O bond distances ranging from 1.80–1.86 Å. H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.71 Å) H–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to three Pb2+, one As3+, and one Cl1- atom. The O–Cl bond length is 3.39 Å. In the second O2- site, O2- is bonded in a 4-coordinate geometry to three Pb2+ and one As3+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two Pb2+, one As3+, and one H1+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to three Pb2+ and one H1+ atom. There are four inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 1-coordinate geometry to five Pb2+ and one O2- atom. In the second Cl1- site, Cl1- is bonded in a 2-coordinate geometry to three equivalent Pb2+ atoms. In the third Cl1- site, Cl1- is bonded in a 4-coordinate geometry to four Pb2+ atoms. In the fourth Cl1- site, Cl1- is bonded in a 4-coordinate geometry to four Pb2+ atoms.
