Untwinned single crystals of the actinomycins D and Z 3 that diffracted to atomic resolution could be obtained for the first time. Low‐temperature data collection and a new ab initio method for solving the structures led to precise crystal structures which showed, for example, that the unit cell of actinomycin D contains three molecules, two of which are present in the form of a hydrogen‐bridged dimer related by a pseudo‐twofold axis (see picture).
