| Abstract
| - We report here a simple one-pot directed synthesis of an oxomolybdate urea composite in which elementary molybdenum oxide building blocks are linked together with the aid of urea. This type of directed material design resulted in large rod-like crystals of an inorganic−organic hybrid extended structure of {MoO3(NH2-CO-NH2)}∞ consisting of right- and left-handed helical units. In the crystal structure urea acts both as a glue that links the inorganic molybdenum units into a helix and as a supramolecular linker for the stabilization of the crystal structure as a whole. This type of molecular topology resulted in an unexpectedly high thermal stability.
- In recent years, several design principles have been applied for the synthesis of extended structures, each with its own complications. In the simple one-pot synthesis reported here, elementary molybdenum oxide building blocks are connected with the aid of urea. The resulting hybrid extended structure contains helices of opposite handedness. This synthetic route opens up new possibilities in designing materials with interesting structural architectures.
