Physical properties

The compound forms crystals of the tetragonal system, space group P4/nmm.

Editorial summary

This brief starts where responsible research should: with the source description of “Erbium oxychloride” as inorganic chemical compound. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current 47-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. The account is most persuasive where Erbium, oxychloride and inorganic can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the science & nature register because the source frames it as inorganic chemical compound. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jul 21, 2025. The linked authority identifier is Q135517199. None of the 0 selected statements returned an explicit reference.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
