More than a hemisphere of reciprocal space was scanned by 0.3\% \w steps,
collecting 1650 frames each at 40 s exposure keeping the detector at 3.0 cm
from the sample. Intensity decay was monitored by recollecting the initial 50
frames at the end of data collection and analysing the duplicate reflections.

A sample of [Re~4~(\m~3~-H)~4~(CO)~12~] dissolved in dichloromethane
was treated at room temperature with 2 equivalents of phthalazine.
The mixture was left at room temperature overnight. Crystals were isolated
by filtration.
