摘要: Abstract Hydrothermal reactions of lead(II) acetate with 5-sulfoisophthalic acid monosodium salt (NaH2BTS) and N-(phosphonomethyl)-N-methylglycine, MeN(CH2CO2H)(CH2PO3H2) (H3L1), or a new aminodiphosphonic acid, 3-Pyridyl-CH2N(CH2PO3H2)2 (H4L2), afforded two novel phosphonate–sulfonate hybrids, namely, Pb3[L1][BTS][H2O]·H2O 1 Pb2[HL3][BTS]·H2O 2 (H2L3=3-Pyridyl-CH2(Me)N(CH2PO3H2)). H2L3 was formed as result the decomposition one phosphonate group in H4L2 during reaction. Compound crystallizes triclinic space P a=9.9148(4) A, b=10.4382(4) A, c=10.6926(2) A, α=96.495(2)°, β=110.599(2)°, γ=98.433(2)°, V=1008.31(6) A3, Z=2. The structure compound features 3D network built from interconnection hexanuclear Pb6(L1)2 units 1D double chains carboxylate–sulfonate. monoclinic P21/c a=9.5403(7) A, b=11.6170(8) A, c=19.7351(15) A, β=97.918(2)°, V=2166.4(3) A3, Z=4. has by cross-linkage phosphonates 2D layers
