Single crystals of three novel transition-metal oxalates, dirubidium di-aqua-dioxalatocobalt(II) dihydrate or dirubidium cobalt(II) bis-(oxalate) tetra-hydrate, Rb[Co(CO)(HO)]·2HO, (I), -poly[dirubidium [[di-chlorido-cobalt(II)]-μ-oxalato]] or dirubidium cobalt(II) dichloride oxalate, {Rb[CoCl(CO)]} , (II), and poly[dipotassium [tri-μ-oxalato-copper(II)dilithium] dihydrate] or dipotassium dilithium copper(II) tris-(oxalate) dihydrate, {K[LiCu(CO)]·2HO} , (III), have been grown under hydro-thermal conditions and their crystal structures determined using single-crystal X-ray diffraction. The structure of (I) exhibits isolated octa-hedral [Co(CO)(HO)] units, whereas (II) consists of chains of Co ions bridged by bidentate oxalato ligands and (III) displays a novel tri-periodic network of Li and Cu ions linked by oxalato bridging ligands.
三种新型过渡金属草酸盐的单晶，二水合二铷二水二草酸根合钴（II）或二铷钴（II）双（草酸根）四水合物，Rb₂[Co(C₂O₄)₂(H₂O)₂]·2H₂O，（I），-聚[二铷[[二氯合钴（II）]-μ-草酸根]]或二铷二氯草酸钴（II），{Rb₂[CoCl₂(C₂O₄)]}ₙ ，（II），以及聚[二钾[三-μ-草酸根合铜（II）二锂]二水合物]或二钾二锂铜（II）三（草酸根）二水合物，{K₂[Li₂Cu(C₂O₄)₃]·2H₂O}ₙ ，（III），已在水热条件下生长，并使用单晶X射线衍射确定了它们的晶体结构。（I）的结构呈现出孤立的八面体[Co(C₂O₄)₂(H₂O)₂]单元，而（II）由通过双齿草酸根配体桥连的Co离子链组成，（III）展示了一个由草酸根桥连配体连接的Li和Cu离子的新型三周期网络。
