We have examined the ground-state properties of the putative intermediate valency and/or charge density wave ͑CDW͒ system Yb 5 Ir 4 Si 10 via resistivity, specific heat, magnetic susceptibility, and x-ray absorption spectroscopy. The bulk properties confirm a CDW-type anomaly at 48 K, but show that all the Yb ions are in an integral trivalent 4f 13 state. Additionally, our low-temperature measurements reveal two magnetic transitions at 2.3 and 1.1 K, respectively. The compound shows
more » ... e-type behavior that might be responsible for the weak-coupling nature of the CDW evidenced by the specific heat data.
