In the crystal structure of the title compound, [Mn(NCSe)(2)(C(4)H(4)N(2))(2)(H(2)O)(2)], the manganese(II) cation is coordinated by two N-bonded pyrimidine ligands, two N-bonded seleno-cyanate anions and two O-bonded water mol-ecules in a distorted octa-hedral coordination mode. The asymmetric unit consists of one manganese(II) cation, located on a centre of inversion, as well as one seleno-cyanate anion, one water mol-ecule and one pyrimidine ligand in general positions. The crystal structure consists of discrete building blocks of composition [Mn(NCSe)(2)(pyrimidine)(2)(H(2)O)(2)], which are connected into layers parallel to (101) by strong water-pyrimidine O-H⋯N hydrogen bonds.
在标题化合物[Mn(NCSe)₂(C₄H₄N₂)₂(H₂O)₂]的晶体结构中，锰(II)阳离子以扭曲的八面体配位模式与两个通过氮原子配位的嘧啶配体、两个通过氮原子配位的硒氰酸根阴离子以及两个通过氧原子配位的水分子配位。不对称单元由位于对称中心的一个锰(II)阳离子以及处于一般位置的一个硒氰酸根阴离子、一个水分子和一个嘧啶配体组成。晶体结构由组成[Mn(NCSe)₂(pyrimidine)₂(H₂O)₂]的离散结构单元构成，这些结构单元通过强的水 - 嘧啶O - H⋯N氢键连接成平行于(101)的层。
