“…As a matter of fact, this lantern-shaped bis(As 3 O 3 )-capped Anderson-type arsenomolybdate is first discovered by Jeannin et al, where a Co-centered arsenomolybdate [Co(H 2 O) 6 ] K 2 [As 6 CoMo 6 O 30 ] was isolated by reaction of [Co(H 2 O) 6 ]Cl 2 , Na 3 [As 3 Mo 3 O 15 ]·10H 2 O, and KCl in aqueous solution at room temperature. Since then, some functionalized bis(As 3 O 3 )-capped M-centered (M = Co, Mo, Cu, Zn, and Ni) Anderson-type arsenomolybdate derivatives are consecutively reported. ,,, In comparison with the previously reported organic–inorganic hybrid bis(As 3 O 3 )-capped, Cu-centered Anderson-type arsenomolybdates (H 2 en)[Cu(en) 2 ][(Cu O 6 )Mo 6 O 18 (As 3 O 3 ) 2 ]·10H 2 O ( A ), [Cu(imi) 2 ] 2 [(CuO 6 )(As 3 O 3 ) 2 Mo 6 O 18 ] [Cu(imi) 2 ] 2 ( B ), and (C 5 H 5 NH) 2 (H 3 O) 2 [(CuO 6 )Mo 6 O 18 (As 3 O 3 ) 2 ] ( C ), their common characteristic is that they all were prepared under hydrothermal conditions by making use of the same copper source of CuCl 2 ·2H 2 O; however, four evident discrepancies between them are also observed. (a) Their arsenic and molybdenum sources are different: As 2 O 3 and (NH 4 ) 6 Mo 7 O 24 ·4H 2 O for 1 and A , NaAsO 2 and (NH 4 ) 6 Mo 7 O 24 ·4H 2 O for B , NaAsO 2 and Na 2 MoO 4 ·2H 2 O for C .…”
