dc.description.abstract	The interplay of nonlocal Coulomb repulsion and Hund’s coupling in the d-orbital manifold in frustrated triangular lattices is analyzed by a multiband extended Hubbard model.We find a rich phase diagram with several competing phases, including a robust pinball liquid phase, which is an unconventional metal characterized by threefold charge order, bad metallic behavior, and the emergence of high-spin local moments. Our results naturally explain the anomalous charge-ordered metallic state observed in the triangular layered compound AgNiO2. The potential relevance to other triangular transition-metal oxides is discussed	en_US
