The material described by N2(Pb2Cl5)2 crystallizes in the monoclinic P2_1/c space group. The structure consists of four ammonia atoms inside a Pb2Cl5 framework. In the Pb2Cl5 framework, there are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 8-coordinate geometry to two equivalent Cl(2), two equivalent Cl(3), two equivalent Cl(4), and two equivalent Cl(5) atoms. In the second Pb site, Pb(2) is bonded in a 7-coordinate geometry to one Cl(3), one Cl(4), one Cl(5), two equivalent Cl(1), and two equivalent Cl(2) atoms. There are five inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a water-like geometry to two equivalent Pb(2) atoms. In the second Cl site, Cl(2) is bonded to two equivalent Pb(1) and two equivalent Pb(2) atoms to form a mixture of distorted corner and edge-sharing ClPb4 trigonal pyramids. In the third Cl site, Cl(3) is bonded in a distorted water-like geometry to one Pb(2) and two equivalent Pb(1) atoms. In the fourth Cl site, Cl(4) is bonded in a distorted trigonal non-coplanar geometry to one Pb(2) and two equivalent Pb(1) atoms. In the fifth Cl site, Cl(5) is bonded in a trigonal non-coplanar geometry to one Pb(2) and two equivalent Pb(1) atoms. is represented by the CIF card [CIF]
