Popis: The three-dimensional hybrid compounds [{Ni6(H2O)10(Bpy)6}V18O51]·1.5H2 O( 1, Bpy = 4,4-bipyridine) and [{Ni(H2O)2(Bpe)}V4O11]·0.5H2 O( 2, Bpe = 1,2-bis(4-pyridyl)ethene) have been synthesized under mild hydrothermal conditions. The 3D crystal structures of both compounds are closely related, with an inorganic honeycomb-like framework stabilized by the organic ligands. The latter are oriented in a crossed way into the channel of the inorganic backbone, and directly attached to the nickel(II) metal centers. Increasing of the ligand length causes widening of the inorganic skeleton with retention of the main structural organization. Both compounds possess self-catenated nets, a 24-nodes net (3-c)2(4-c)3(5-c)7 for 1 and a binodal net (4-c) (7-c) for 2. These rigid architectures exhibit very interesting thermal properties. The co-crystallized water molecules can be removed without changes in the crystal structures. The ini
