Ln(o-HOC6H4CO2)3(H2O)2·2H2O [Ln = Tb, Ho], Mr = 642. 32 (648. 33 )**,monoclinic, space group Cc,a=16. 280(4)(16. 217 (2)) ,b= 14. 889(3) (14. 877(2)),c = 9.867(1)(9. 835(2)) A,β=101.49(1)(101. 46(1))°,Z= 4,V= 2343. 8(7)(2325. 3(6)) A3,Dc=1. 8(1. 85)g·cm-3,μ=31. 6(36. 1)cm-1(MoKa), F(000) = 1272(1280).The final R=0. 031(0. 031),Rw = 0. 029(0. 031). There is no discrete molecules of the compounds in the crystal structures. The compounds are in linear polymeric arrangements, each metal ion is bridged to the next by two bridging carboxyl groups from salicylato ions.
