Abstract
[NiL3]C4O4 [L = 1,2-ethanediamine (en) and 1,2-N,N′-dimethylethanediamine (N,N′-dmen)], [NiL3]C4O4·nH2O [for L = 1,2-N-methylethanediamine (meen) and 2-methyl-1,2-propanediamine (ibn); n = 1, and for L = 1,2-propanediamine (pn); n = 2], and [NiL2C4O4]·2H2O [L = 1,2-N-ethylethanediamine (eten), 1,2-N-propylethanediamine (pren), 1,2-N,N-dimethylethanediamine (N,N-dmen) and 1,2-N,N′-diethylethanediamine (N,N′-deten)] have been synthesized by the addition of the respective diamines to finely powdered nickel(II)squarate dihydrate, NiC4O4·2H2O. All of the tris-species, except for [Ni(N,N′-dmen)3]C4O4 were also prepared by adding diamines to NiC4O4·2H2O dissolved in aqueous ammonia (25%). When the latter method was followed, the bis-species [NiL2C4O4] [L = eten, pren, 1,2-N-isopropylethanediamine (ipren), N,N-dmen, N,N′-dmen, and N,N′-deten] were also obtained. [NiL2C4O4] (L = en, meen, N,N′-dmen, pn, and ibn) were also prepared from their corresponding tris(diamine) species upon heating in the solid state. [Ni(...
