A family of benzotriazole based coordination compounds, obtained in two steps and good yields from commercially available materials, formulated [CuII(L 1 )2(MeCN)2]·2(ClO4)·MeCN (1), [CuII(L 1 )(NO3)2]·MeCN (2), [ZnII(L 1 )2(H2O)2]·2(ClO4)·2MeCN (3), [CuII (L 1 )2Cl2]2 (4), [CuII 5(L 1 )2Cl10] (5), [CuII 2(L 1 )4Br2]·4MeCN·(CuII 2Br6) (6), [CuII(L 1 )2(MeCN)2]·2(BF4) (7), [CuII(L 1 )2(CF3SO3)2] (8), [ZnII(L 1 )2(MeCN)2]·2(CF3SO3) (9), [CuII 2(L 2 )4(H2O)2]·4(CF3SO3)·4Me2CO (10) and [CuII 2(L 3 )4(CF3SO3)2]·2(CF3SO3)·Me2CO (11) are reported. These air stable compounds were tested as homogeneous catalysts for the A3 coupling synthesis of propargyl amine derivatives from aldehyde, amine and alkyne under a non-inert atmosphere. Fine-tuning of the catalyst resulted in a one dimensional (1D) coordination polymer (CP) (8) with excellent catalytic activity in a wide range of substrates, avoiding any issues that would inhibit its performance.
