Popis:	A general synthetic approach to rationalize the solution preparative chemistry of oxovanadium phosphates containing organic species as structural directing agents is presented. Careful attention is payed to the hydrolysis and condensation processes involving the ionic species in solution, and a simple restatement of the partial charge model (PCM) has been used in order to organize the experimental results. The structure of a new V(IV)−Fe(III) bimetallic oxovanadium phosphate, [H3N(CH2)2NH3]2[H3N(CH2)2NH2] [FeIII(H2O)2(VIVO)8(OH)4(HPO4)4(PO4)4]·4H2O, has been determined by X-ray single crystal diffraction methods. This compound crystallizes in the monoclinic system, space group P21/n and the cell dimensions are as follows: a = 14.383(3) A, b = 10.150(2) A, c = 18.355(4) A, and β = 90.39(3)° (Z = 2). The existence of a complex intercrossing channel system, including a very large channel of 18.4 A of diameter (in which both water molecules and ethylenediamine species are located), is the more interesting fe...
