英文摘要	Two novel edta-linked 4f-3d heterometallic two-dimensional coordination polymers Nd2Mn3(edta)(3) (H2O)(11) . 12H(2)O (A) and Gd2Co3(edta)(3)(H2O)(11) . 12H(2)O (B) were synthesized by reaction of Ln(OH)(3) (Ln = Nd, Gd), MnCO3 or Co(OH)(2) with H(4)edta (edta = ethylenediamine-NNN'N'-tetra-acetate) in water. A and B crystallize in the monoclinic space group C2 with cell parameters a=16.003(3), 15.799(5), b=14.733(3), 14.603(5), c=14.819(3), 14.690 Angstrom, beta = 116.21(2), 116.64(3)degrees, V = 3135(1), 3029(2) Angstrom(3), and Z=2. A or B consists of a two-dimensional heterometallic sheet in which the Ln(III) ion is ten coordinated by six carboxyl oxygen atoms from edta and four oxygen atoms from H2O molecules, the M(II) ion is seven coordinated by two nitrogen, four oxygen from edta and one oxygen from H2O molecule: Each Ln(III) ion has three M(II) neighbours, while each M(II) is connected to two Ln(III) ions. The Ln(III) and M(II) ions are linked by tridendate bridging carboxylate oxygen atoms with considerable short Ln-M separations in the range of 4.82 to 4.90 Angstrom, which are shorter than the distances between metal ions in heterometallic 3d complexes of edta. The heterometallic sheets are connected by H2O molecules through hydrogen bonds. (C) 1998 Elsevier Science Ltd.
