 Title    One-and Two-Dimensional Copper(I) Halide Based Coordination Polymers with Bridging Pyridazine or Pyrimidine Ligands  
 Abstract    1-Dimensional coordination polymers J. [CuX(/i-pydz)] 1 -3 (X = Cl, Br, I; pydz = pyrid­ azine) may be prepared by self-assembly in acetonitrile solution at 120 °C (1) or room temper­ ature (2, 3). Individual chains contain (CuX)2 rings and dimeric [Cu(^-pydz)]2 substructures. At a 2:1 molar ratio treatment of Cul with pydz in acetonitrile affords the lamellar complex ^ [(Cul)2(/i-pydz)] (4) whose novel ^ [(Cul)2] sheets contain fused 4-, 6-and 8-membered (Cul)" rings and are stabilized by pydz bridging between adjacent Cu atoms. In contrast, l_ [(CuBr)2(/i-pym)2] (5) (pym = pyrimidine) contains separated J. [CuBr] chains and (CuBr)2 rings as participating building units.

 Title    Three-dimensional Copper(I) Halide Based Coordination Networks with Asymmetrically Substituted Bridging N-Donor Ligands  
 Abstract    The discrete complex [(Cul)2 (pyzCN)4] (1) and the coordination polymers ^ [CuI(pyzCN)] (2) and 3 [(CuX)3 (pyzCN)2] (3, 4; X = Br, Cl) may be prepared from the respective copper(I) halide CuX and 2-cyanopyrazine (pyzCN) by self-assembly in acetonitrile solution at 100-120°C. Whereas 2 exhibits 1 [Cul] staircase double chains as its characteristic substructure, the three-dimensional netwo'rks of 3 and 4 contain single zigzag CuX strings. The influence of the copper(I) halide on both the connectivity pattern and the dimensionality of a resulting coordination network is particularly apparent for the 1:1 complexes ^ [CuI(pymMe)] (5), 3 [(CuBr)3(pymMe)_3] (6) and ^ [CuCl(pymMe)] (7), which were generated by reaction of öaX with 4-methylpyrimidine (pymMe) under reaction conditions similar to those above.
