PbC2NH2Br2 crystallizes in the monoclinic C2/m space group. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 7-coordinate geometry to one N(1), two equivalent Br(2), and four equivalent Br(1) atoms. The Pb(1)-N(1) bond length is 2.74 Å. Both Pb(1)-Br(2) bond lengths are 2.95 Å. There are two shorter (3.09 Å) and two longer (3.34 Å) Pb(1)-Br(1) bond lengths. In the second Pb site, Pb(2) is bonded in a 7-coordinate geometry to one N(2), two equivalent Br(2), and four equivalent Br(1) atoms. The Pb(2)-N(2) bond length is 2.74 Å. Both Pb(2)-Br(2) bond lengths are 2.94 Å. There are two shorter (3.09 Å) and two longer (3.34 Å) Pb(2)-Br(1) bond lengths. There are four inequivalent C sites. In the first C site, C(1) is bonded in a distorted trigonal planar geometry to one C(3), one N(1), and one H(1) atom. The C(1)-C(3) bond length is 1.40 Å. The C(1)-N(1) bond length is 1.34 Å. The C(1)-H(1) bond length is 1.09 Å. In the second C site, C(2) is bonded in a distorted trigonal planar geometry to one C(4), one N(2), and one H(2) atom. The C(2)-C(4) bond length is 1.40 Å. The C(2)-N(2) bond length is 1.34 Å. The C(2)-H(2) bond length is 1.09 Å. In the third C site, C(3) is bonded in a distorted trigonal planar geometry to one C(1), one N(1), and one H(3) atom. The C(3)-N(1) bond length is 1.34 Å. The C(3)-H(3) bond length is 1.09 Å. In the fourth C site, C(4) is bonded in a distorted trigonal planar geometry to one C(2), one N(2), and one H(4) atom.

In the first N site, N(1) is bonded in a distorted bent 120 degrees geometry to one Pb(1), one C(1), and one C(3) atom. In the second N site, N(2) is bonded in a distorted bent 120 degrees geometry to one Pb(2), one C(2), and one C(4) atom. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(2) atom. In the third H site, H(3) is bonded in a single-bond geometry to one C(3) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one C(4) atom. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded to two equivalent Pb(1) and two equivalent Pb(2) atoms to form a mixture of distorted edge and corner-sharing BrPb4 trigonal pyramids. In the second Br site, Br(2) is bonded in a bent 120 degrees geometry to one Pb(1) and one Pb(2) atom. Linkers: 2 c1cnccn1. Metal clusters: 4 [Pb].
