This paper classifies Hermitian structures on 6-dimensional nilmanifolds M=\Ga\bsGM=\Ga\bs G for which the fundamental 2-form is \pd\opd\pd\opd-closed, a condition that is shown to depend only on the underlying complex structure J of M. The space of such J is described when G 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.
