CuC12H16(NO)2(ClO4)2 is Indium-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four hypochlorous acid;trihydrate molecules and two CuC12H16(NO)2 clusters. In each CuC12H16(NO)2 cluster, Cu(1) is bonded in a square co-planar geometry to two equivalent N(1) and two equivalent O(1) atoms. Both Cu(1)-N(1) bond lengths are 1.96 Å. Both Cu(1)-O(1) bond lengths are 2.03 Å. There are six inequivalent C sites. In the first C site, C(1) is bonded in a distorted trigonal planar geometry to one C(2), one N(1), and one H(3) atom. The C(1)-C(2) bond length is 1.39 Å. The C(1)-N(1) bond length is 1.35 Å. The C(1)-H(3) bond length is 1.09 Å. In the second C site, C(2) is bonded in a distorted single-bond geometry to one C(1), one C(3), and one H(4) atom. The C(2)-C(3) bond length is 1.40 Å. The C(2)-H(4) bond length is 1.09 Å. In the third C site, C(3) is bonded in a trigonal planar geometry to one C(2), one C(4), and one C(6) atom. The C(3)-C(4) bond length is 1.40 Å. The C(3)-C(6) bond length is 1.50 Å. In the fourth C site, C(4) is bonded in a distorted single-bond geometry to one C(3), one C(5), and one H(5) atom. The C(4)-C(5) bond length is 1.39 Å. The C(4)-H(5) bond length is 1.09 Å. In the fifth C site, C(5) is bonded in a distorted trigonal planar geometry to one C(4), one N(1), and one H(6) atom. The C(5)-N(1) bond length is 1.35 Å. The C(5)-H(6) bond length is 1.09 Å. In the sixth C site, C(6) is bonded in a distorted water-like geometry to one C(3) and two equivalent H(7,8) atoms. Both C(6)-H(7,8) bond lengths are 1.10 Å. N(1) is bonded in a trigonal planar geometry to one Cu(1), one C(1), and one C(5) atom. There are seven inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(1) atom. The H(1)-O(1) bond length is 0.99 Å. In the second H site, H(2) is bonded in a single-bond geometry to one O(1) atom. The H(2)-O(1) bond length is 0.99 Å. In the third H site, H(3) is bonded in a single-bond geometry to one C(1) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one C(2) atom. In the fifth H site, H(5) is bonded in a single-bond geometry to one C(4) atom. In the sixth H site, H(6) is bonded in a single-bond geometry to one C(5) atom. In the seventh H site, H(7,8) is bonded in a single-bond geometry to one C(6) atom. O(1) is bonded in a distorted water-like geometry to one Cu(1), one H(1), and one H(2) atom.
