The present. paper reports the results obtained with the method of "polycrystalline ENDOR crystallography" of 31 P transitions of some bis (disubstituted-dithiophos-phinato)copper(II) complexes, magnetically diluted in the corresponding Nj(II), Pd(II) and Pt(II) host lat.ticcs. Two distinct. types of 31 p ENDOR transitions have been detected for all samples -local 31 P (-4iso ca. 17 MHz and /laniso ca. 0.7 MHz), and distant. 31p {J-liso ca. 0.9 MHz and Aaniso ca. 0.2 MHz). Data. confirm that; the principal directions of both 31 p coupling tensors coincide. Conclusion on the cases of arising distant ENDOR transition pairs is made on the basis of EN DOR, single crystal EPR and X-ray data.
