NMR study of covalency in K2FeCl5 center dot H2O.

The Cl-35 NMR in K2FeCl5 (.) H2O has been observed in the antiferromagnetic state in zero magnetic field. By comparing the experimental NMR frequencies with ones calculated by solving the secular equation, the chlorine NMR parameters have been obtained. The results are discussed in comparison with those of the polarized neutron diffraction. (c) 2006 Elsevier B.V. All rights reserved.
