J. Pickardt et B. Staub, METAL(II) DIAZINE COMPLEXES - CRYSTAL-STR UCTURES OF CD(PYRAZINE)BR-2, CD(PYRAZINE)I-2, CU(PYRAZINE)CL-2, AND CD(PYRIMIDINE)(NO3)(2)CENTER-DOT-2H(2)O, Zeitschrift fur Naturforschung. B, A journal of chemical sciences, 52(12), 1997, pp. 1456-1460
Single crystals of the compounds Cd(pyrazine)Br-2, Cd(pyrazine)I-2, Cu
(pyrazine)Cl-2 and Cd(pyrimidine)(NO3)(2) . 2H(2)O were obtained by cr
ystallisation from aqueous solutions of the metal salts and solutions
of the respective diazine in an organic solvent. The structures of the
pyrazine complexes consist of ''supramolecular'' networks of -M-pyraz
ine-M- and -M-(mu(2)-Hal)(2)-M- chains. The pyrimidine complex shows a
three dimensional network due to -M-pyrimidine-M- chains connected vi
a hydrogen bonds between H(H2O) and O(ONO2).
