A new dinuclear zinc(II) complex, [Zn2Br2L2] (I), was prepared from 4-methyl-2-[(2-methylaminoethyl-imino)methyl]phenol (HL) with zinc bromide in methanol. Self-assembly of I with ammonium thiocyanate in methanol afforded the mononuclear complex [Zn(L)(HL)]2[Zn(NCS)4] (II). Structures of complexes I, II have been characterized by elemental analysis, IR spectra and single crystal X-ray diffraction (CIF files CCDC nos. 1046617 (I), 1046618 (II)). Complex I possesses a crystallographic two-fold rotation axis symmetry, with Zn···Zn separation of 3.106(1) Å. Complex II contains two mononuclear zinc(II) complex cations and one [Zn(NCS)4] complex anion. The Zn(1) atom in I is in a tetrahedral coordination. The Zn(2) atom in I and the Zn atoms in II are in octahedral coordination. Crystals of I, II complexes are stabilized by hydrogen bonds.
