Bis(µ(2)-2-phen-oxy-propionato-κO:O')bis-[(1,10-phenanthroline-κN,N')bis-(2-phen-oxy-propionato-κO,O')ytterbium(III)].

In the centrosymmetric binuclear title complex, [Yb(2)(C(9)H(9)O(3))(6)(C(12)H(8)N(2))(2)], the two Yb(III) ions are linked by two 2-phen-oxy-propionate (L) groups in a bidentate bridging mode. Each Yb(III) ion is eight-coordinated by two O atoms from two bridging L ligands, four O atoms from two chelating L groups and two N atoms from one chelating phen mol-ecule in a distorted YbN(2)O(6) dodeca-hedral geometry.
