The compound described by PbAsO2Cl crystallizes in the orthorhombic P2_12_12_1 space group. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 5-coordinate geometry to one O(2), one O(3), one O(4), one Cl(1), and one Cl(2) atom. In the second Pb site, Pb(2) is bonded in a 2-coordinate geometry to one O(3), one O(4), one Cl(1), and one Cl(2) atom. There are two inequivalent As sites. In the first As site, As(1) is bonded in a distorted T-shaped geometry to one O(1), one O(2), and one O(4) atom. In the second As site, As(2) is bonded in a distorted T-shaped geometry to one O(1), one O(2), and one O(3) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one As(1) and one As(2) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Pb(1), one As(1), and one As(2) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to one Pb(1), one Pb(2), and one As(2) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Pb(1), one Pb(2), and one As(1) atom. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in an L-shaped geometry to one Pb(1) and one Pb(2) atom. In the second Cl site, Cl(2) is bonded in a 1-coordinate geometry to one Pb(1) and one Pb(2) atom. is represented by the CIF file [CIF]
