(CH2)2(C4NH10)2CuC2H2O5Cl2 is Indium-derived structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of four 02329_fluka molecules, four tetramethylammonium molecules, and two CuC2H2O5Cl2 clusters. In each CuC2H2O5Cl2 cluster, Cu(1) is bonded in a square pyramidal geometry to one O(1), one O(2), one O(5), one Cl(1), and one Cl(2) atom. The Cu(1)-O(1) bond length is 1.99 Å. The Cu(1)-O(2) bond length is 1.99 Å. The Cu(1)-O(5) bond length is 2.29 Å. The Cu(1)-Cl(1) bond length is 2.30 Å. The Cu(1)-Cl(2) bond length is 2.30 Å. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(3) atom. The C(1)-O(1) bond length is 1.28 Å. The C(1)-O(3) bond length is 1.25 Å. In the second C site, C(2) is bonded in a distorted bent 120 degrees geometry to one O(2) and one O(4) atom. The C(2)-O(2) bond length is 1.28 Å. The C(2)-O(4) bond length is 1.25 Å. There are two inequivalent H sites. In the first H site, H(26) is bonded in a single-bond geometry to one O(5) atom. The H(26)-O(5) bond length is 0.99 Å. In the second H site, H(25) is bonded in a single-bond geometry to one O(5) atom. The H(25)-O(5) bond length is 0.99 Å. There are five inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Cu(1) and one C(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Cu(1) and one C(2) atom. In the third O site, O(3) is bonded in a single-bond geometry to one C(1) atom. In the fourth O site, O(4) is bonded in a single-bond geometry to one C(2) atom. In the fifth O site, O(5) is bonded in a distorted water-like geometry to one Cu(1), one H(25), and one H(26) atom. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a single-bond geometry to one Cu(1) atom. In the second Cl site, Cl(2) is bonded in a single-bond geometry to one Cu(1) atom.
