Coinage metal(M)-pyrazolate(pz)systerms are of interest containing Pz-bridged metal cluster and showing the luminescence rooted in Pz-M charge transfer(LMCT)and metal-centered transition(MC).1 As prototype of this sort of compounds,a series of trimeric and tetrameric Cu(Ⅰ),Ag(Ⅰ)and Au(Ⅰ)pyrazolates have been synthesized and photophysically investigated.2,3 In an aim to obtain the photoluminous coordination polymers with [Cu(Pz)]x motifs as luminophores and to practically embody the effect of temperature on the assemblies of coordination polymers,a mixture of AgNO3 and 2,7-bis(3,5-dimethyl-1H-pyrazol-4-yl)benzo[lmn][3,8]phenanthroline-1,3,6,8(2H,7H)-tetraone(H2L)in molar ratio of 1∶4 was treated in a mixed n-hexane/CH3CN(v/v = 1∶1)solvent and NH3.H2O(5 drops)at 120℃ and 140℃ and so obtained two polymers formulated as [Ag3(L)1.5(CH3CN)]n(1)and [Ag2(L)0.5(CN)]n(2)respectively(Fig.1).Of note is that the kinetically favored product 1 contains acetonitrile molecule as second ligand,but the thermodynamically favored 2 contains the cyanide in-situ produced from hydrolysis of acetonitrile as linking ligand,thereby illustrating an effect of temperature on the reactivity of introduced coordinating solvent and further the structures of Ag(Ⅰ)coordination polymers.
