This paper classifies Hermitian structures on 6-dimensional nilmanifolds for which the fundamental 2-form is -closed, a condition that is shown to depend only on the underlying complex structure of . The space of such is described when is the complex Heisenberg group, and explicit solutions are obtained from a limaçon-shaped curve in the complex plane. Related theory is used to provide examples of various types of Ricci-flat structures.
