M—H -0 interactions involving bridging hydride ligands in the crystal

M—H—M bridge bonding. Two metal hybrids and the H Is overlap in the same region of space. Filling the resulting combination with two electrons gives the two-electron three-center bond proposed for these systems.

M—X-Ray diffraction patterns of melezitose, sucrose from melezitose, natural sucrose, and turanose. The diagrams were made by Mr. William C. White of the National Institutes of Health.
