The crystal and molecular structure of (..mu..-H)/sub 2/Os/sub 3/(CO)/sub 10/(..mu..-CH/sub 2/) has been determined by using single-crystal neutron diffraction. The complex crystallizes in the orthorhombic space group Pn2/sub 1/a with lattice parameters at 110 K of a = 18.502(9), b = 10.096(5), and c = 8.763(4)A. The molecule consists of a triangular array of Os atoms with one nonbridged edge (Os-Os = 2,855(3)A), one edge bridged by a single hydride (Os-Os = 3.053(3)A), and a third edge doubly bridged by a hydride atom and a methylene ligand (Os-Os = 2,824(3)A). The complex contains no terminal hydride ligands. The methylene carbon atom has a distorted tetrahedral geometry with an Os-C-Os angle of 82.1(1)/sup 0/ and a H-C-H angle of 106.0(8)/sup 0/.
