Syntheses and crystal structures of di-chlorido-bis(2,3-di-methyl-pyrazine-κ<i>N</i>)zinc(II) and <i>catena</i>-poly[[di-chlorido-zinc(II)]-μ-2,3-di-methyl-pyrazine-κ² <i>N</i> ¹:<i>N</i> ⁴].

ABSTRACT: The reactions of zinc(II)chloride with 2,3-di-methyl-pyrazine (C₆H₈N₂) in different ratios in aceto-nitrile lead to the formation of [ZnCl₂(C₆H₈N₂)₂] (1) and [ZnCl₂(C₆H₈N₂)] _n (2). The asymmetric unit of 1 consists of one Zn cation located on a twofold rotation axis, one chloride anion and one 2,3-di-methyl-pyrazine ligand that occupy general positions. In compound 2 the asymmetric unit is built up of one zinc cation, two chloride anions and one 2,3-di-methyl-pyrazine ligand that are located in general positions in the uncommon trigonal space group P3₂. In compound 1, the Zn cations are tet
