Abstract
Adducts of sodium perchlorate, sodium thiocyanate, and lithium perchlorate with NN′-ethylenebis(salicylideneiminato)- and NN′-ethylenebis(acetylacetoneiminato)-nickel(II) are reported. All have alkali-metal ion: nickel complex ratios of 1 : 2. The title complex crystallizes in the space group C2/c with a= 19.728(4), b= 10.832(2), c= 15.012(3)Å, β= 112.85(8)°, and Z= 4. The X-ray structure determination (heavy-atom method, 2 549 unique reflections measured by a four-circle diffractometer, R 0.04) has shown that the Na+ ion lies on a crystallographic two-fold axis with an irregular six-fold co-ordination sphere defined by oxygen atoms from two nickel complexes and a disordered perchlorate anion.Keywords
