摘要：

A new heterometallacrown coordination polymer [K2Cu(NPA)(2)(H2O)(4)](n) (where H(2)NPA = 3-nitro-phthalic acid) has been synthesized and it's crystal structure has been elucidated. In the complex, the o-phthalate group coordinates to metal atoms behaving as both tetradentate and heptadentate coordination, the modes of which have been found for the first time. The thermal behaviors of this complex and the thermal decomposition kinetics have been studied. Kinetic analysis shows that the decomposition of title complex in the main range acts as two separate transitions with the first one being a double-step following reaction, A ->(F1) B ->(Fn) C, and the second being a three-step following reaction of t:f,f, A ->(F2) B ->(F2) C ->(R2) D. The kinetic parameters of these processes were also obtained. (c) 2005 Elsevier B.V. All rights reserved.
