Talk:Zinc hydride

Hydrolysis Conditions

I read the "decomposes slowly at room temperature and quickly above ?? degrees", but I could only get "hydrided" zinc sheets (overcharged battery electrodes, absorbed bubbling hydrogen) to decompose this way if they were in water. (back to zinc, releasing hydrogen - days if cold, tens of minutes(?) in hot water. They had been in room or hot air for weeks with no apparent change.) I'm not sure enough of myself to edit the article, but did an author neglect to mention it has to be in water to decompose it? CraigxC (talk) 04:01, 8 February 2019 (UTC)CraigxC

That's because you didn't have pure zinc hydride. Hydrogen-charged zinc is not the same, it is metallic zinc with most of the hydrogen content in the form of a dissolved gas, and only trace quantities of actual zinc hydride. Plasmic Physics (talk) 04:20, 8 February 2019 (UTC)

Structure of ZnH₂

The linear polymeric structure for ZnH₂ described in the article: is this proven or is it just a sensible conjecture of the review authors being quoted in Wikipedia as fact? The reference used for the one dimensional polymeric structure is "Grochala, Wojciech; Edwards, Peter P. (18 February 2004). "Thermal decomposition of the non-interstitial hydrides for the storage and production of hydrogen". Chemical Reviews 104 (3): 1283–1316. doi:10.1021/cr030691s." Hopefully in this there is a reference to a paper describing the crystal structure. Axiosaurus (talk) 09:54, 3 September 2013 (UTC)

Until a source is found that contains experimental evidence, the qualifier segment which I added could suffice to address the issue. Plasmic Physics (talk) 12:46, 3 September 2013 (UTC)

That certainly addresses the issue. Thanks. Axiosaurus (talk) 12:55, 3 September 2013 (UTC)
