The problem is the low magnetogyric ratio of 163Dy it gives a resonance frequency of about 23 MHz. It is unlikely that Varian will have supplied you with a probe or an amplifier capable of going down that low.

There would be limited information you could get from the spectrum anyway a spin 5/2 nucleus has a quadrupole moment which will broaden the resonances though this may not be too bad for ions due to their (approximately) spherical symmetry. Also bear in mind in the solid state there are also internuclear dipole-dipole interactions which can be quite large.

Is the compound diamagnetic?

Do you have access to an EDX? That might be an option at least for the stoichiometry. If you need chemical shifts you can also apply for XANES but that's a synchrotron method which isn't always available and quite expensive.
