The crystal crystallizes in a triclinic system, space group P1 with a= 1.306 3(2) nm , b=1.319 4(4) nm, c=1.950 2(4) nm, α=90.597(14)°, β= 93.998(11)° , γ=94.093(13)°, V=3.344 1(12) nm3, Z=2, the final R indices are R 1= 0.065 4 , wR 2=0.126 2 respectively. The complex contains a novel tetranuclear cluster cation with four Er 3+ ions connected by four μ 3OH ions and six bridging carboxyl groups. Each erbium ion is coordinated by three μ 3OH, three carboxylic oxygen atoms from three αalanine and two oxygen atoms from water molecules, forming a squareantiprismatic coordination polyhedron.展开更多
