(1,10-phen)2Mo3O9: a new one-dimensional organic/inorganic hybrid material consisting of two {MoO4N2} octahedra and one {MoO4} tetrahedron alternately

A new one-dimensional organic/inorganic hybrid, (1,10-phen)2Mo3O9 (1), has been prepared by a hydrothermal method using (nBu4N)2Mo6O19 and 1,10-phenanthroline and structurally characterized. The compound crystallizes in the monoclinic space group C2 with a=14.9794(3), b=9.7102(2), c=10.3280(2) Å, β=118.0949(6)°, V=1325.23(5) Å3, Z=2, and R1=0.0335, wR2=0.0877. The structure consists of a chain of corner-sharing {MoO4N2} octahedra and {MoO4} tetrahedra that alternate such that each {MoO4N2} octahedron corner-shares with another such octahedron and an {MoO4} tetrahedron; consequently, each {MoO4} tetrahedron corner-shares with two {MoO4N2} octahedra. The chains in the crystal are parallel to each other along both b and c axes and form pseudo-two-dimensional channels through the hydrogen bonds along both a and b axes.
