the crystal structure of the corresponding isotypic cobalt salt CoK2P4O12 · 5H2O because of the lack of NiK2P4O12 · 5H12O single crystals. The symmetry is monoclinic, P21c, a = 12.995(2), b = 16.294(2), c = 7.432(2) Å, β = 92.17(1)°, Z = 4, and R = 0.033 for 3122 independent reflections. H atoms have been located and refined. A detailed IR study of both NiK2P4O12 · 5H2O and CoK2P4O12 · 5H2O is reported
为了确定镍二钾cyclotetraphosphate七水合物的脱水过程中发生的重组,NIK 2 P 4 ø 12 ·7H 2 O(A. Jouini,M. Dabbabi,和A.杜瑞夫,J.固态化学式 60中, 6(1985) ),由于缺乏NiK 2 P 4 O 12 ·5H 12 O单晶,我们研究了相应的同型钴盐CoK 2 P 4 O 12 ·5H 2 O的晶体结构。对称性是单斜的,P21c,a = 12.995(2),b = 16.294(2),c = 7.432(2)Å,β= 92.17(1)°,对于3122次独立反射,Z = 4,R = 0.033。H原子已被定位和精制。报道了对NiK 2 P 4 O 12 ·5H 2 O和CoK 2 P 4 O 12 ·5H 2 O的详细红外研究,并提出了脱水和重组的初步解释。
