In search for biocompatible hydrophilic polymers suitable for preparation of delivery systems of boron cluster compounds with high loading capacity, we studied the interaction of metallacarborane sodium [3-cobalt(III) bis(1,2-dicarbollide)] with poly(2-ethyloxazoline) (PEOX) and with a double-hydrophilic block copolymer poly(ethylene oxide)-block-poly(2-ethyloxazoline) (PEO–PEOX) in aqueous solutions by a combination of scattering, microscopy, spectroscopy, and thermochemistry techniques. The paper is a contribution to our long-time study of novel hybrid nanostructures based on hydrophilic polymer–metallacarborane complexes.
