The Cu(Ⅱ) and Co(Ⅱ) supramolecular coordination polymers,[CuCl2(DPO)-(CH3CN)0.5(CH2Cl2)0.5]n(CuDPO,DPO=rctt-1,3-diphenyl-2,4-bis[2-(5-phenyl)oxazolyl]cyclo-butane) and [CoCl2(DPO)]n(CoDPO),were synthesized and characterized by single-crystal X-ray diffraction method.CuDPO crystallizes in monoclinic,space group P21/n,with a=11.243(5),b=16.070(8),c=19.872(9) ,β=95.678(10)°,Z=4,V=3573(3) 3,C35.50H28.50Cl3CuN2.50O2,Mr=692.00,Dc=1.287 g/cm3,μ=0.868 mm-1,F(000)=1420,S=1.089,(△/σ)max=0.069,the final R=0.0682 and wR=0.1749.CoDPO is of monoclinic,space group P21/n,with a=11.396(4),b=15.151(5),c=17.673(6) ,β=90.528(6)°,Z=4,V=3051.4(17) 3,C34H26Cl2CoN2O2,Mr=624.40,Dc=1.359 g/cm3,μ=0.770 mm-1,F(000)=1284,S=0.981,(△/σ)max=0.001,the final R=0.0471 and wR=0.0961.In each case,the metal cation is coordinated by two Cl anions and two N atoms from oxazole ring of the ligands,which leads to the formation of a one-dimensional polymeric structure.It is found that the cyclobutane ring of coordinated DPO adopts a distorted conformation in the crystal,which is attributed to the increased steric effect between adjacent aryl substituents for the coordination of oxazole ring to metal cation.Thermal gravimetric analysis of the two complexes was also observed.
The Cu (Ⅱ) and Co (Ⅱ) supramolecular coordination polymers, [CuCl 2 (DPO) - (CH 3 CN) 0.5 (CH 2 Cl 2) 0.5] n (CuDPO, DPO = rctt-1,3-diphenyl- - (5-phenyl) oxazolyl] cyclo-butane and [CoCl2 (DPO)] n (CoDPO) were synthesized and characterized by single-crystal X-ray diffractometry.CuDPO crystallizes in monoclinic, space group P21 / n, with a = 11.243 (5) b = 16.070 (8) c = 19.872 (9) β = 95.678 (10) ° Z = 4 V = 3573 (3) 3 C35.50H28.50Cl3CuN2.50O2 , The final R = 0.0682 and the wR = 0.1749. The results are shown in the following table. The results are as follows: Mr = 692.00, Dc = 1.287 g / cm3, μ = 0.868 mm-1, F (000) = 1420, S = 1.089, is of monoclinic space group P21 / n with a = 11.396 (4) b = 15.151 (5) c = 17.673 (6) β β = 90.528 (6) ° Z = 4 V = 3051.4 ) 3, C34H26Cl2CoN2O2, Mr = 624.40, Dc = 1.359 g / cm3, μ = 0.770 mm-1, F (000) = 1284, S = 0.981, (△ / σ) max = 0.001, wR = 0.0961. In each case, the metal cation is coordinated by two Cl anions and two N atoms from oxazole ring of the ligands, which leads to the formation of one one-dimensional polymeric structure. It is found that the cyclobutane ring of coordinated DPO adopts a distorted conformation in the crystal, which is attributed to the increased steric effect between adjacent aryl substituents for the coordination of oxazole ring to metal cation. happy gravimetric analysis of the two complexes was also observed.
