Crystal and Molecular Structures of Phosphonolactone Derivatives of Chromone

Interplay of thermochemistry and Structural Chemistry, the journal (volume 16, 2005) and the discipline

“…As chromone (benzo-c-pyrone) derivatives form a class of biologically important compounds Małecka et al [121] performed X-ray structure analysis of a new class of phosphonolactone derivatives of the chromone hydrazonium salt and its acid. For both structures short atom-atom contacts, which can be recognized as hydrogen bonds, were found.…”
