Abstract
During the preparation of calcium bilirubinate (CaBR) single crystals, brown crystals were grown in a gel solution of CaCl2/Sodium bilirubinate. X-ray diffraction analysis proved that the crystal was calcite. FTIR investigations support this result. However, the subtracted spectra revealed that the CaBR dispersed in the crystals and interacted with calcite on the molecular level, since the maximum band shift of the CaBR in calcite from the correspond bands of CaBR was ca. 20 cm-1. It was confirmed that microstructure also by x- ray diffraction and photoacoustic Fourier transform infrared spectroscopy.
