Synthesis and crystal structure of Na2Zn(OH)(4)

Crystallization from saturated sodium hydroxozincate solutions yields colou rless platelets of crystals of Na2Zn(OH)(4). The X-ray structure determinat ion on these crystals was successful including all hydrogen positions. P2(1)/n, Z = 4, a = 7.959(3) Angstrom, b = 6.534(1) Angstrom, c = 8.501(3) Angstrom, beta = 93.97(3)degrees, N(F-o(2) greater than or equal to 2 sigma F-o(2)) = 1668, N(Var.) = 81, R-1/wR(2) = 0.043/0.107. Na2Zn(OH)(4) crystallizes in a layered structure. Alternate layers contain Na+ in octahedral and Zn2+ in tetrahedral coordination by OH-.
