Hi Andre,

for me it looks like a phosphonic acid derivative. A coupling constant of ~600 Hz is typical for a 1JP,H coupling in phosphonic acids. On your last slide it can be seen that there is a lot of phosphorous in both of your samples which correlates with my assumption. Have you already performed 31P experiments?

Best wishes,
Markus.
