The title compound, [Mn(C(6)H(4)N(5)O)(2)(H(2)O)(4)], is isotypic with its Zn, Ni and Cd analogues reported recently. In the crystal, the Mn(II) cations are coordinated by four O atoms from four aqua ligands and two N atoms from two 5-(pyridin-4-yl)tetra-zolide N(5)-oxide ligands in a distorted octa-hedral coordination environment. The asymmetric unit consists of one Mn(II) cation located on a crystallographic twofold axis, and two crystallographically independent water mol-ecules and one N-donor ligand in general positions. The discrete complex mol-ecules are arranged in alternating rows parallel to [100] and are linked by O-H⋯N and O-H⋯O hydrogen bonds into a three-dimensional network.
标题化合物[Mn(C₆H₄N₅O)₂(H₂O)₄]与其最近报道的锌、镍和镉类似物同晶型。在晶体中，Mn(II)阳离子在扭曲的八面体配位环境中由来自四个水合配体的四个O原子和来自两个5-(吡啶-4-基)四唑N(5)-氧化物配体的两个N原子配位。不对称单元由位于晶体学二重轴上的一个Mn(II)阳离子、两个晶体学独立的水分子和一个处于一般位置的N供体配体组成。离散的配合物分子平行于[100]交替排列成行，并通过O-H⋯N和O-H⋯O氢键连接成三维网络。
