摘要

The new coordination compounds [CuCl_2(C_5H _(14)N_2)_2]·4 H_2O (1) and [Co(CO_3)(C_5H_(14)N_2) _2]Cl·H_2O (2) (C_5H_(14)N _2 = 2,2-dimethylpropyldiamine) were synthesized under solvothermal conditions. Compound 1 crystallizes in the monoclinic space group P2 _1 with a = 6.2175(4), b = 27.4152(17), c = 11.7975(8), β = 97.702(8)°, V = 1992.8(2) ~3, Z = 4 and 2 in the monoclinic space group P2_1/c with a = 11.5913(8), b = 22.4797(12), c = 7.3655(5), β = 96.760(8)°, V = 1905.9(2) ~3, Z = 4. In 1 the Cu ~(2+) cation is octahedrally coordinated by two bidentate 2,2-dimethylpropyldiamine molecules in the basal plane and two Cl~- anions located at the apices. The Cu-Cl bond lengths are very unsymmetrical which is caused by the significantly different hydrogen bonding interactions of the two Cl- anions. The H_2O molecules are joined by strong H?O interactions generating a (H_2O)_(10) decamer which are fused to form a wavy water layer. The layer displays a new and hitherto never observed H_2O layer motif which may be described as L10(6). In 2 the Co~(2+) cation is surrounded by two bidentate amine molecules and a bidentate CO_3~(2-) anion which was formed in situ by CO_2 uptake from the atmosphere. N-H, O and Cl are involved in an extended hydrogen bonding networks leading to the formation of layers which are arranged generating channels along [0 0 1] which are occupied by water molecules. Thermal investigations of both compounds exhibit complex decomposition patterns and successive emission of the constituents. The optical band gaps of 3.79 for 1 and 3.48 eV for 2 confirm that both compounds are isolators.
