title: Influence of liquid structure on the thermodynamics of freezing.
abstract: The ordering transitions of a two-dimensional lattice liquid characterized by a single favored local structure (FLS) are studied using Monte Carlo simulations. All eight distinct geometries for the FLS are considered and we find a variety of ordering transitions: first order, continuous, and multistep transitions. Using an entropy-energy representation of the freezing transition we resolve the dual influence of the local structure on the ordering transition, i.e., via the energy of the crystal and the entropy cost of structure in the liquid.
