Zn(CH3)2 is Indium-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four dimethylzinc molecules. Zn(1) is bonded in a linear geometry to two equivalent C(1,2) atoms. C(1,2) is bonded to one Zn(1); one H(1); one H(2); and one H(3,5) atom to form corner-sharing CZnH3 tetrahedra. There are five inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1,2) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(1,2) atom. In the third H site, H(3,5) is bonded in a single-bond geometry to one C(1,2) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one C(1,2) atom. In the fifth H site, H(6) is bonded in a single-bond geometry to one C(1,2) atom.
