Аннотация
A new four-core silver complex {Ag4[NH(CH2PO3H)3]2(H2O)2} · H2O has been synthesized and investigated. Its crystallographic characteristics are sp. gr. \(P\bar 1\), Z = 1, a = 7.5806(2) Å, b = 8.4946(2) Å, c = 10.1092(3) Å, α = 81.087(2)°, β = 88.356(2)°, γ = 82.132(2)°. The ligand in the form of zwitterion is hexdentate. The complex is chelating; each silver atom closes an eight-membered cycle Ag–O–P–C–N–C–P–O. Simultaneously, two ligand molecules form six bridge bonds with neighboring formula units. Silver atoms form a polycyclic cluster Ag4O6, the configuration of which is stabilized by coordination and hydrogen bonds.
