摘要：

Three new lanthanide complexes with the formulae [EU2(TsGly)(6)(phen)(2)(H2O)(2)] (1), [Ln(TsGly)(2)(phen)(2)(H2O)(2)]Cl(.)2H(2)O [Ln=Er (2a) and Yb (2b), TsGly=N-p-tolylsulfonylglycinate, phen=1,10-phenanthroline] were synthesized. Crystallographic data for 1: monochnic, P2(1)/n, a=1.29791(16) run, b=1.9034(2) nm, c=1.7596(2) nm,beta=93.410(3)degrees, V=4.3394(9) nm(3),Z=4,R-1=0.0326, wR(2)=0.0771; and for 2b: triclinic, P1, a=1.2674(2) mn, b=1.4405(2) nm, c=1.4809(3) nm, alpha=113.256(3)degrees, beta=108.253(3)degrees, gamma=94.739(3)degrees, V=2.2922(7) nm(3), Z=2, R-1=0.0292, wR(2)=0.0669. X-ray diffractional analysis reveals that compound 1 adopts dinuclear structure with fourfold bridging TsGly ligands between the Eu(III) centers, while compound 2b features an unusual mononuclear structure.
