Abstract

In the title cobalt(II) coordination polymer with isobutyrate ligands, {[Co{CH(CH)CO}(HO)]·HO} , the Co ion is hexa-coordinated in a slightly distorted octa-hedral coordination environment defined by two O atoms from two bridging water mol-ecules and four O atoms from four bridging carboxyl-ate ligands. The carboxyl-ates adopt two different coordination modes, μ-(κ:') and μ-(κ:), forming a one-dimensional polymeric chain extending along [010]. The intra-chain cobalt⋯cobalt separation is 3.2029 (2) Å. The polymeric chains are linked by hydrogen bonds involving the water mol-ecules of solvation, giving a two-dimensional network structure lying parallel to (100).

摘要

在标题化合物具有异丁酸盐配体的钴（II）配位聚合物{[Co{CH(CH)CO}(HO)]·HO} 中，钴离子在由两个桥连水分子的两个氧原子和四个桥连羧酸盐配体的四个氧原子所定义的略微扭曲的八面体配位环境中呈六配位。羧酸盐采取两种不同的配位模式，μ-(κ:')和μ-(κ:)，形成沿[010]方向延伸的一维聚合物链。链内钴⋯钴间距为3.2029 (2) Å。聚合物链通过涉及溶剂化水分子的氢键相连，形成平行于(100)的二维网络结构。
