A bimetallic oxide hybrid material constructed from a coordination complex polymer and molybdenum oxide subunits, [Ni(3,4′-bipyridine)2MoO4]·3H2O

The hydrothermal reaction of NiCl2·6H2O, MoO3, 3,4′-bipyridine (3,4′-bpy) and H2O in the mole ratio 1.0:1.0:2.1:1500 yields [Ni(3,4′-bpy)2MoO4]·3H2O (1·3H2O) in 80% yield. The structure of 1·3H2O consists of a three-dimensional coordination polymer {Ni(3,4′-bpy)2}n2n+ with entrained {MoO4}2− tetrahedra and with water molecules of crystallization occupying channels within the bimetallic oxide–ligand framework. Crystal data: C20H16N4O4NiMo·3H2O (1·3H2O), tetragonal P41212, a=13.1866(5) Å, c=29.458(2) Å, V=5122.3(4) Å3, Z=8, Dcalc=1.532 g cm−3.
