Dimers are a girl's best friend: The rhombic dimer [(LiH)2] (see calculated structure) is the major product of the reaction of laser-ablated lithium atoms in solid H2 upon annealing or irradiation with visible light. Irradiation also produces the higher clusters [(LiH)n] (n=3,4). Like the more stable lithium halide dimers, the rhombic dimer [(LiH)2] is highly ionic.
