Abstract

A model for red azo pigment Ca4B was characterized structurally using synchrotron radiation. This highly anisotropic ladder structure represents a new structural class in azo pigment chemistry. The picture shows that the calcium atoms coordinate in a complex manner to three azo ligands (one terdentate, one bidentate, and one monodentate) and two water molecules simultaneously.
