The new compound, [CuCl( phen ) 2 ] 3 H 3 V 10 O 28 · 7 H 2 O, was prepared by reaction of an aqueous KVO 3 solution (pH 3) with an aqueous solution of CuSO 4 · 5 H 2 O in which 1,10‐phenanthroline ( phen ) and KCl were added. The crystal structure of the compound was determined, and the proton position in H 3 V 10 O 28 3– were calculated by the bond length/bond number method and also determined from difference electron density map. The protons are bound to colinearly arranged μ –OV 2 and μ –OV 3 groups which is the common protonation type in trihydrogen decavanadates. The structure crystallizes in P1 space group symmetry.
