ABSTM_02 When printed, the submitted absorption T values will be replaced by the scaled T values. Since the ratio of scaled T's is identical to the ratio of reported T values, the scaling does not imply a change to the absorption corrections used in the study. Ratio of Tmax expected/reported 0.769 Tmax scaled 0.769 Tmin scaled 0.587

Single crystals of (I) were grown from methanothermal reaction containing nickel (0.059 g, 1 mmol), antimony (0.122 g, 1 mmol) and selenium (0.237 g, 3 mmol). The reactants were weighed and mixed in a glove-box under a nitrogen atmosphere. The reactants were then loaded into a Teflon-lined steel autoclave and 3 ml of methanol/1,2-ethanediamine (volume ratio = 1:4) was added. The reaction took place at 443 K over a period of 4 d. The product was filtered off and washed with acetone. The title compound is unstable in air, and must be stored under a nitrogen atmosphere.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Chalcogenidometallates with open frameworks have attracted considerable interest as possible zeolite-like materials, of which highly interesting properties could be expected. In recent decades, a large number of thioantimonates exhibiting different degrees of fused SbxSy anionic fragments have been reported (Sheldrick & Wachhold, 1997, 1998). In these compounds, the connections between of the complex anions lead to diverse structures. Compounds with one-, two-, and three-dimensional structures have been isolated and characterized. In contrast to the thioantimonates, the chemistry of heavier chalcogenoantimonates is less developed probably due to the ease of hydrolysis of seleno- and telluro-antimonates. By using solvothermal synthesis, the structures of [Mn(en)3]2·[Mn4(en)9(SbSe4)4]·2H2O (en is 1,2-ethylenediamine; Bensch et al., 1997), [enH][Mn(en)3][SbSe4] (Wendland & Bensch, 1998), Cu2SbSe3.0.5 en and Cu2SbSe3.en (Chen et al., 1998), [Fe(en)3]2(Sb2Se5) (Chen et al., 2000) and [enH][Fe(en)3][SbSe4] (Girard & Li, 1998) have been reported. In our recent investigations, we have obtained a new complex, namely enH·Ni(en)3·SbSe4, (I), which, to our best knowledge, is the first selenoantimonates containing Ni(en)32+ as a structure-directing agent. Herein, we report the synthesis and crystal structure of (I).
The asymmetric unit of (I) comprises isolated Ni(en)32+, monoprotonated ethylenediamine cation, and SbSe43− anion (Fig. 1). In the complex cation, the Ni atom is surrounded by six N atoms from three neutral ethylendiamine (en) ligands, that function as a bidentate ligands, forming five-membered chelate rings, with Ni—N bond lengths ranging from 2.108 (3) to 2.130 (3) Å, to give a distorted octahedral environment. The configuration of the en rings in Ni(en)32+ is Λ(δδλ) or Δ(λλδ) according to Saito's description (Saito, 1979). It is noteworthy that the C—C bond distance [C11—C12 = 1.420 (8) Å] in the en ligand with λ conformation is significantly shorter than those [C15—C16 = 1.506 (5) Å and C13—C14 =1.497 (6) Å] in the other two en ligands with δ conformation. A similar situation was found in the configuration of [Fe(en)3]2+ in the compound [enH][Fe(en)3][SbSe4] (Girard & Li, 1998).
The Sb—Se distances of the tetrahedral SbSe43− anion in (I) range from 2.4722 (8) to 2.4810 (11) Å, which are consistent with those found in analogous compounds (Wendland & Bensch, 1998; Sheldrick & Wachhold, 1996). As shown in Fig. 2, the Ni(en)32+ cations and their crystallographic inversion center related species can be considered as constructing cationic slabs along the a and c axes, between which the SbSe43− and protonated ethylenediamine species are located. The protonated H atom is assigned on atom N21 rather than on atom N22 due to the closer cation–anion contact (2.54 Å; Pell & Ibers, 1996). Atom Se2 of the isolated SbSe43− anion acts as a hydrogen-bond acceptor, forming an intermolecular hydrogen bond with the N atom of protonated enH; N21···Se2i = 3.306 (6) Å, H···Se2i =2.54 Å and N21—H···Se2 = 145° [symmetry code: (i) 1 − x, −y, 1 − z].
