The construction of non-trivial SU(3) structures on Calabi-Yau manifolds and their possible application to string compactifications is explored. Among the wide range of SU(3) structures which emerge we find Strominger-Hull systems, suitable for heterotic or type II string compactifications, on all complete intersection Calabi-Yau manifolds. Provided they can be supported by suitable sources in the Bianchi identity, they lead to Calabi-Yau compactifications of string theory with a non Ricci-flat, physical metric which can be written down explicitly and in analytic form.
