  摘要：

  The use of succinamic acid (H(2)sucm) in Cu-II/N,N',N ''-donor [2,2':6',2 ''-terpyridine (terpy), 2,6-bis(3,5-dimethylpyrazol-1-yl)pyridine (dmbppy)] reaction mixtures yielded compounds [Cu(Hsucm)(terpy)](n)(ClO4)(n) (1), [Cu(Hsucm)(terpy)(MeOH)](ClO4) (2), [Cu-2(Hsucm)(2)(terpy)(2)](ClO4)(2) (3), [Cu(ClO4)(2)(terpy)(MeOH)] (4), [Cu(Hsucm)(dmbppy)](n)(NO3)(n)center dot 3nH(2)O (5.3nH(2)O), and [CuCl2(dmbppy)]center dot H2O (6 center dot H2O). The succinamate(-1) ligand exists in four different coordination modes in the structures of 1-3 and 5, i.e., the mu(2)-kappa O:kappa O':kappa O '' in 1 and 5 which involves asymmetric chelating coordination of the carboxylato group and ligation of the amide O-atom leading to 1D coordination polymers, the mu(2)-kappa O-2:kappa O' in 3 which involves asymmetric chelating and bridging coordination of the carboxylato group, and the asymmetric chelating mode in 2. The primary amide group, either coordinated in 1 and 5, or uncoordinated in 2 and 3, participate in hydrogen bonding interactions, leading to interesting crystal structures. Characteristic IR bands of the complexes are discussed in terms of the known structures and the coordination modes of the Hsucm(-) ligands. The thermal decomposition of complex 5 center dot 3nH(2)O was monitored by TG/DTG and DTA measurements. (C) 2010 Elsevier Ltd. All rights reserved.

  pyridine (L1py), respectively. The conformation of the pyrazole rings in the solid-state structures of both L0py and L1py were anti due to relatively low repulsion between the alkyl substituents. Both copper(II) chlorido complexes [CuCl2(L0py)] and [CuCl2(L1py)] were five-coordinate with solid-state structures best described as distorted square-pyramidal geometry involving N3Cl2 donor sets.
