The molecular structure of 2-ferrocenyl-2-[(2-ferrocenylethenyl)(morpholin-4-yl)methyl]-1,3-dithiolane, [Fe2(C5H5)2(C19H21NOS2)] or C29H31Fe2NOS2, has the ferrocenyl fragments in a trans disposition with respect to the vinyl group. One of the methylene groups is disordered over two sites with occupancies of 0.782 (13):0.218 (13). In the crystal, cyclopentadienyl-C—H...O(morpholinyl) interactions feature within helical chains parallel to the c-axis direction. The chains are connected by methylene- and cyclopentadienyl-C—H...O(cyclopentadienyl) interactions.
