A new hydrogen-bonding linked 3-D polyoxomolybdate

• Mixed polyhedra linked through both edge and corner sharing that are further connected by hydrogen bonds.
• The structure displayed a novel 3-D structure with 2-D layered covalent networks.
• The 3-D structure is revealed the first time with detailed structural analysis.

The reactions under hydrothermal reaction conditions resulted in a hydrogen-bonding linked polyoxomolybdate [(NH4)2M4O13]n1 with three-dimensional (3-D) polymeric structure. The compound 1 is composed of three distinct (MoO6) and one (MoO5) mixed polyhedral connected by edge-sharing within the asymmetric unit displaying a covalent bonding four-step ladder network, and the ladder units linked via corner-sharing between asymmetric units showing an extended covalent bonding 2-D layer structure, and the 2-D networks are further linked by multiple hydrogen bonds to result in a 3-D polyoxomolybdate.
