The new molecular metal chalcogenoantimonate, 2-aminoethylammonium tris(1, 2-ethylenediamine)cobalt tetraselenoantimonate, [enH][Co(en)3][SbSe4] (en = ethylenediamine), has been synthesized by solvothermal reaction in...The new molecular metal chalcogenoantimonate, 2-aminoethylammonium tris(1, 2-ethylenediamine)cobalt tetraselenoantimonate, [enH][Co(en)3][SbSe4] (en = ethylenediamine), has been synthesized by solvothermal reaction in an ethylenediamine/methanol solution at 443 K and structurally characterized by X-ray crystallography. The crystal belongs to triclinic, space group P1 with a = 8.900(4), b = 9.663(5), c = 14.361(6) ? = 104.783(18), = 92.4220(10), = 109.9920(10), C8H33CoN8SbSe4, Mr = 737.94, V = 1110.7(10) ?, Z = 2, Dc = 2.207 g/cm3, F(000) = 702, = 8.525 mm-1, R = 0.0648, wR = 0.0755 and S = 1.005. The structure contains tetrahedral [SbSe4]3- anion and octahedral [Co(en)3]2+ cation, as well as the monoprotonated ethylenediamine cation [enH]+.展开更多
