ABSTRACT: In the crystal structure of the title compound, [Zn(3)(NCSe)(4)(OH)(CN)(C(4)H(4)N(2))(4)](n) one of the two crystallograph-ically independent zinc(II) cations is coordinated by two terminal N-bonded seleno-cyanato anions and two N atoms of two symmetry-related pyridazine ligands in a trigonal-bipyramidal geometry, while the other zinc(II) cation is coordinated by one terminal N-bonded seleno-cyanato anion, one μ-1,2-cyanido anion and three N atoms of three crystallographically independent pyridazine ligands in a slightly distorted octa-hedral coordination geometry. The zinc(II) atoms are further connected via a μ(3)-hydroxido anion into trinuclear building blocks. The formula unit consists of three zinc cations, four seleno-cyanato anions, one μ(3)-hydroxido anion, four pyridazine mol-ecul
