The thermal desorption temperature Td of single-cation borohydrides was found to decrease with increasing the value of the Pauling electronegativity χP of the cation (metal). We examined T d of double-cation borohydrides ZrLin-4(BH 4)n, and then the correlation between Td and χP determined for single-cation borohydrides is extended to double-cation ones. Td for ZrLin-4(BH4) n with the composition n from 4 to 6 continuously increases from 440 K to 650 K, and approaches that of LiBH4, 740 K: Td correlates with the averaged χP calculated from n. The extended correlation might lead to precise adjustments in the thermodynamical stabilities of borohydrides.
