The crystal structures of two hydrothermally synthesized AgCu-arsenates were determined by single crystal X-ray work: Ag 5 Cu(AsO 4 )(As 2 O 7 ) [ a  = 5.859(1),  b  = 9.019(2),  c  = 10.384(2) Å,  α  = 97.18(2),  β  = 90.98(2),  γ  = 92.11(2)°, space group  P [unk],  Z  = 2,  R w   = 0.034 for 5827 observed data and 185 variable parameters] and Ag 7 Cu(As 2 O 7 ) 2 Cl [ a  = 10.335(2),  b  = 8.992(2),  c  = 16.546(3) Å,  β  = 95.21(2)°, space group  C c,  Z  = 4,  R w   = 0.035 for 3202 observed reflections and 243 variable parameters]. The environment of the Cu atom in Ag 7 Cu(As 2 O 7 ) 2 Cl is peculiar: the Cu–O bond lengths of 1.914(7), 1.945(6), 2.136(8), 2.147(7), 2.250(8), and 2.344(7) Å show an uncommon [2+2+2] coordination (distorted octahedron). The two Cu atoms in Ag 5 Cu(AsO 4 )(As 2 O 7 ) are [4] and [4+2] coordinated, all the Ag atoms are irregularly [5], [6], and [7] coordinated to O (and Cl) atoms. The geometry of the pyroarsenate groups are compared to data from literature.
