We study electronic properties of a new planar carbon crystal formed throughnetworking biphenylene molecules. Novel electronic features among carbonmaterials such as zone-center saddle point and peculiar type-II Dirac fermionicstates are shown to exist in the low energy electronic spectrum. The type-IIstate here has a nearly flat branch and is close to a transition to type-I.Possible magnetic instabilities related with low energy bands are discussed.Furthermore, with a moderate uniaxial strain, a pair of Dirac points merge withthe zone center saddle point, realizing concurrent Lifshitz transitions of vanHove singularity as well as pair annihilation of the Dirac fermions. A neweffective Hamiltonian encompassing all distinctive low energy states isconstructed, revealing a finite winding number of the pseudo-spin texturearound the Dirac point, quantized Zak phases, and topological grain boundarystates.
