Hydrothermal synthesis and X-ray structure: a reduced titanic molybdenum(V) phosphate (NH3CH2CH2NH2)(5)Na [Ti2Mo12O30(PO4)(HPO4)(4)(H2PO4)(3)]center dot 6H(2)O

A novel titanic molybdenum(V) phosphate (NH3CH2CH2NH2)(5)Na [Ti2Mo12O30(PO4 ) (HPO4)(4)(H2PO4)(3)](.)6H(2)O crystallizes in the triclinic space group P 1 with a = 12.057(3) Angstrom, b = 14.668(2) Angstrom, c = 21.2680(10) Angs trom, alpha = 80.840(10)degrees, beta = 82.960(10)degrees, gamma = 76.65(2) degrees, and D-c = 2.707 g cm(-3) for Z = 2, Refinement based on 12,037 obs erved reflections led to R = 0.0609. The result of single crystal x-ray dif fraction revealed the presence of a tunnel and two crystallographically ind ependent clusters in the solid state structure. The plane layers in its sol id-state structure are interconnected in-sheet (axial) through multipoint h ydrogen bonding between the ethylenediamine nitrogen atoms and the cluster oxygen atoms.
