W2(CO)3 crystallizes in the orthorhombic Cmmm space group. W(1) is bonded in a 6-coordinate geometry to one C(2), two equivalent C(1), one O(1), and two equivalent O(2) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded to two equivalent W(1), one C(1), and two equivalent C(2) atoms to form distorted CW2C3 trigonal bipyramids that share corners with two equivalent C(1)W2C3 trigonal bipyramids, edges with two equivalent C(2)W2C4 octahedra, and edges with three equivalent C(1)W2C3 trigonal bipyramids. In the second C site, C(2) is bonded to two equivalent W(1) and four equivalent C(1) atoms to form distorted CW2C4 octahedra that share edges with two equivalent C(2)W2C4 octahedra and edges with four equivalent C(1)W2C3 trigonal bipyramids. There are two inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to two equivalent W(1) atoms. In the second O site, O(2) is bonded in a linear geometry to two equivalent W(1) atoms.
