Magnetic properties of LiBeH3 and Li2BeH4

LiBeH3 and Li2BeH4 have previously been proposed as candidates for high-temperature superconductivity because positions of hydrogen atoms in the respective crystal structures may lead to the formation of hydrogen-atom-based conduction bands. In the present work, the magnetization of LiBeH3 and Li2BeH4 was measured as a function of applied magnetic field and temperature with a superconducting quantum interference device (SQUID) magnetometer. Small magnetic-susceptibility values and the highly reactive nature of the samples led to the use of a background correction procedure involving the raw SQUID data. The magnetization data for LiBeH3 and Li2BeH4 samples appear to exhibit a superposition of both weak diamagnetic and superparamagnetic behaviors, and show no irreversibility with respect to either temperature or applied magnetic field within experimental uncertainty. At T = 300 K, diamagnetic components of susceptibilities are observed to be -3.3 ±0.1 × 10-6 emu/mol for LiBeH3 and -3.1±0.1 × 10-6 emu/mol for Li2BeH4. Furthermore, the possible origin of the observed superparamagnetic contribution is discussed. These measurements are contrasted with previous work, which had suggested that the magnetic behavior of Li2BeH4 could be related to type-II superconductivity.

A matrix-isolation and density functional theory study of the reactions of laser-ablated beryllium, magnesium, and calcium atoms with methane

Beryllium atoms produced by laser ablation have been co-condensed with methane/argon mixtures onto a substrate at 10 K. Infrared spectroscopy has been used to identify a number of organoberyllium products, viz. CH3BeH, CH3BeCH3, CH3Be, H2CBeH, and HCBeH. Assignments of the infrared absorption bands are made on the basis of 2H and 13C substitution and by comparison with frequencies supplied by DFT calculations. In the reaction of magnesium or calcium atoms with methane, the only insertion product that could be identified was the monomethyl metal hydride, CH3MH (M = Mg or Ca).
