(Cu(OOCC6H4COO))2Si(C3H2)4 is Indium-derived structured and crystallizes in the tetragonal P4_2/mmc space group. The structure is zero-dimensional and consists of two tetrakis(prop-1-en-2-yl)silane molecules and two Cu(OOCC6H4COO) clusters. In each Cu(OOCC6H4COO) cluster, Cu(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(1) atoms. All Cu(1)-O(1) bond lengths are 1.96 Å. There are three inequivalent C sites. In the first C site, C(2) is bonded in a distorted single-bond geometry to one C(4) and one H(2) atom. The C(2)-C(4) bond length is 1.34 Å. The C(2)-H(2) bond length is 0.95 Å. In the second C site, C(5) is bonded in a distorted bent 120 degrees geometry to one C(4) and two equivalent O(1) atoms. The C(5)-C(4) bond length is 1.53 Å. Both C(5)-O(1) bond lengths are 1.25 Å. In the third C site, C(4) is bonded in a trigonal planar geometry to one C(5) and two equivalent C(2) atoms. H(2) is bonded in a single-bond geometry to one C(2) atom. O(1) is bonded in a distorted bent 120 degrees geometry to one Cu(1) and one C(5) atom.
