PdSe2: enthalpy of formation

3 accepted literature formation-enthalpy value(s) (experimental 1, model 2).

Literature values

Enthalpy of formation of PdSe2 reported in the literature (3)
Value	Phase as printed	T (K)	Class	System	Source	Location
-86.4 kJ/mol (basis unstated) ± 1.8	PdSe2	298.15	experimental	Pd–Se	[1] Bordier 2014 cites Stolyarova 2011 doi	Table 2, p. 3, row 3 report
-86.67 kJ/mol (basis unstated)	PdSe2	298.15	model	Pd–Se	[1] Bordier 2014	Table 3, p. 7, row 8 report
-86.4 kJ/mol (basis unstated) ± 1.8	PdSe2	298.15	model	Pd–Se	[1] Bordier 2014 cites Stolyarova 2011 doi	Table 3, p. 7, row 7 report

Uncertainty budget

Components kept separate, in the value's unit (literature SCHEMA.md, UNCERTAINTY_CALIBRATION.md): effective = max(sqrt(max(printed, reading, method)^2 + composition^2 + conversion^2), scatter). The method floor is the robust between-study scatter of the method class in ORCHID (calibrated) or a documented prior; printed values and printed uncertainties are unchanged.

Version 1, machine-extracted: values were read by language-model readers constrained to quote their source and checked automatically, and the release was then audited on the printed pages by adversarial audits, an independent second review of fit-facing records and a preliminary human review of a frozen sample. Flags such as accepted and ESPEI-ready record screening results, not certification; known issues are listed in the release notes.
