We present the first example of a compound containing Ba2+, C2O42-, water and some additional halide or pseudo-halide anions, viz. hexa-mu2-aqua-mu6-oxalato-dibarium(II) diisothiocyanate, [Ba2(C2O4)(H2O)62]n. The structure consists of positively charged planar covalent layers of Ba2+ cations, oxalate anions and water molecules. The first coordination sphere of the Ba2+ cation contains six water molecules and four O atoms from two planar oxalate anions. The oxalate anion lies on an inversion centre and is coordinated to six Ba2+ cations, each donor O atom being bonded to two cations. Pairs of water molecules are coordinated by two Ba2+ cations. The layers are interspersed with non-coordinated NCS- anions.
我们展示了第一个含有Ba2+、C2O42-、水和一些额外卤离子或拟卤离子阴离子的化合物实例，即六-μ2-水-μ6-草酸根-二钡（II）二异硫氰酸酯，[Ba2(C2O4)(H2O)62]n。该结构由带正电的Ba2+阳离子、草酸根阴离子和水分子的平面共价层组成。Ba2+阳离子的第一配位层包含六个水分子和来自两个平面草酸根阴离子的四个O原子。草酸根阴离子位于对称中心，与六个Ba2+阳离子配位，每个供体O原子与两个阳离子键合。成对的水分子由两个Ba2+阳离子配位。这些层穿插着未配位的NCS-阴离子。
