In the title complex, [Ag(C(7)H(10)N(2)O(2)S)(2)]NO(3), the Ag(I) cation is bicoordinated in an almost linear configuration by two N-donor atoms of the thia-zole rings of two distinct ethyl 2-amino-4-thia-zoleacetate (EATA) ligands. The dihedral angle between the two thia-zole rings is 49.9°. A weak Ag⋯O (2.729 Å) inter-action between the Ag cation and one of the O atoms from the nitrate anion is observed, and a pseudo-dimer is formed through a weak Ag⋯S (3.490 Å) inter-action between the Ag cation and the S atom of the thia-zole ring of a symmetry-related mol-ecule. In the crystal structure, there are intra- and inter-molecular N-H⋯O hydrogen bonds. The occurrence of inter-molecular N-H⋯O hydrogen bonds results in the formation of two-dimensional sheets parallel to (010), which are further linked into a three-dimensional network through weak C-H⋯O inter-actions.
在标题配合物[Ag(C₇H₁₀N₂O₂S)₂]NO₃中,Ag(I)阳离子由两个不同的2-氨基-4-噻唑乙酸乙酯(EATA)配体的噻唑环的两个N供体原子以几乎线性的构型进行双配位。两个噻唑环之间的二面角为49.9°。观察到Ag阳离子与硝酸根阴离子的一个O原子之间存在弱的Ag⋯O(2.729 Å)相互作用,并且通过Ag阳离子与对称相关分子的噻唑环的S原子之间的弱Ag⋯S(3.490 Å)相互作用形成了一个假二聚体。在晶体结构中,存在分子内和分子间的N-H⋯O氢键。分子间N-H⋯O氢键的存在导致形成了平行于(010)的二维片层,这些片层通过弱的C-H⋯O相互作用进一步连接成三维网络。
