Abstract

The nuclear quadrupole interaction of 187W(β-)187Re in W(VI)-EDTA complexes at room temperature was determined by time differential perturbed angular correlations (TDPAC) to be VQ = 1270(8) MHz with an asymmetry parameter η= 0.403(4). While the coordination geometry of the Mo(VI)- EDTA complex is known, there appears to be none for the W-analogue. The rather similar asymmetry parameters for the 187W(β-)187Re in W(VI)-EDTA complex and for the 99Mo(β-)99Tc in Mo(VI)- EDTA complex, determined previously, supports the idea that the coordination geometries in the Moand W-complexes are similar
