Ethylenediamine manganese(II) selenite, a new hybrid inorganic/organic network containing MnO5N octahedra and SeO3 pyramids

(en)Mn2(V2O7): A 3D manganese vanadate built by Mn–O layers and two types of pillars of V2O7 and en bridges

“…Compared with the related inorganic compound of Mn 2 (V 2 O 7 ) based on the linkages of the Mn-O sheets and V 2 O 7 units, its Mn-O sheet and linking mode between the sheets are different from 1. Although the Mn-O sheet of manganese selenite [14] is similar to that of 1, every vacant square is decorated by a selenite group and the en molecules only play the role of single bridges between Mn-Se layers.…”

“…Up to now, several manganese vanadates brought about by diamine have been reported, in which the Mn 2+ ions are usually coordinated with O or F atoms, sometimes with N atoms of organic amine. Notice that the organoamine seldom acts as bidentate ligand covalently-bonded to Mn 2+ ions, which only appeared in zinc borates [13] and manganese selenite [14]. More importantly, inorganic and organic double bridges between sheets have not been observed in manganese vanadates.…”
