Corner sharing tetrahedral network in Co3(HAT)[N(CN)2]6(OH2)2 (HAT=1,4,5,8,9,12-hexaazatriphenylene)

We report a trinuclear Coll complex containing bridging dicyanamides and a tris-chelated HAT, which possesses similar to37% void space. The magnetic exchange pathways appear in the structure as a corner sharing tetrahedral network. The compound crystallizes in the monoclinic space group P2(1)/c [a = 13.655(3) Angstrom, b = 15.189(3) Angstrom, c = 22.367(4) Angstrom, beta = 114.100(2)degrees, V = 4234.5(14) Angstrom(3), Z = 4, R(F-o) = 0.0823]. The magnetic data were fit to an S = 3/2 model for systems dominated by zero-field splitting effects with g = 2.01 and D = 38.9 cm(-1).
