-N-(dimethylphosphinoyl)benzenesulfonamidato]]The crystal structure of the title calcium complex, [Ca(C8H11NO5PS)2]n, is composed of a polymeric chain, which is formed due to two bridging sulfonyl groups linking CaII ions in a O-S-O-Ca manner. Thus, the coordination environment of the CaII ions is composed of six O atoms belonging to the phosphoryl and sulfonyl groups of two chelate rings and two additional O atoms of two bridging sulfonyl groups. The coordination polyhedron of the central atom (2 symmetry) has a distorted octahedral geometry.
The synthesis of H(sp) was carried out according to previously reported method (Kirsanov, 1952; Kirsanov et al., 1954). Calcium (0,01 g, 0,25 mmol) was dissolved in 5 ml of hot methanol and combined with a hot solution H(sp) (0,133 g, 0,5 mmol) in metanol (5 ml). The mixture was heated to 330 K for about 30 min. Colourless crystals of complex suitable for X-ray diffraction separated over a period of 7 days; they were washed with dry propan-2-ol and dried in vacuo at room temperature (0,134 g, 94%). Analysis found: IR (KBr pellet, cm-1): 1220, 1060 (s, SO2) and 1190 (s, PO).
All hydrogen atoms were located from electron density difference maps and included in the refinement in the riding motion approximation with Uiso constrained to be 1.5 times Ueq of the carrier atom for the methyl groups and 1.2 times Ueq of the carrier atom for the other atoms.

Experimental. Empirical absorption correction using spherical harmonics, implemented in SCALE3 ABSPACK scaling algorithm. |
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. |

The coordination compounds of Group 2 metals with O,O - donor ligands have attracted much recent interest as potential precursors for the deposition of a range of electro-ceramic oxides by metal-organic chemical vapour deposition (MOCVD) (Wojtczak et al., 1996; Purdy et al., 1989). Various β- diketonate complexes of Group 2 have been proposed to preparation of deposit films of metals and metal oxides (Oehr et al., 1988; Berry et al., 1988).
N - Phosphorylated sulfonylamides (PS) of a general formula RSO2NHPO(R')2 can be considered as SNP - heterosubstituted structural analogues of β- diketones (HAD). They may be regarded as powerful chelating systems for various metal ions and coordination chemistry of HAD remains to be relatively wide elaborated (Pietraszkiewicz et al., 2002).
The sulfonylamido-group –SO2NH– has been found as a key structural motif shared by a large number of bioactive compounds, spanning a wide variety of biological effects, such as antimicrobial activity, specific enzyme inhibition, hormone regulation, and among others used as chemotherapics (Anand, 1996).
The phosphorylic group in PS ligands possess high nucleophilic affinity. It can be used for obtaining of stable molecular or ionic [M(L)2]-, [M(L)2]0 and [M(L)2]+ species based on s-, p- and d-elements. Herein we report the synthesis and X-ray studies of coordination compound Ca(II) with dimethyl(phenylsulfonyl)amidophosphate.
There are no close contacts between the neighboring chains in the crystal (Fig. 1). The molecular species [Ca(sp)2] forms a polymer around the symmetry centre at x,y, z + 3/2 on calcium atom which is situated in the special position; Ca is immersed in a six-coordination environment provided by two bidentate sp- anion through sulfonyl O1 and phosphoryl O3 O atoms, and O2 of sulfonyl group connected in the bridge manner to the neighboring Ca atom. The resulting coordination polyhedron has the shape of slightly distorted octahedron with phosphoryl oxygen atoms {O3 and O3i} occupying the axial vertexes. The values of some bond lengths and angles are given in the Table 1. The angle O3 Ca1 O3i has 152.17 (8)° and the corresponding distance Ca1 - O3 is 2.3055 (15) Å. [c.f. the sum of effective ionic radii are M2++O2-(Ca, O)=2.35 Å] (Shannon, 1976); the mean deviation from plane O1O2O1iO2iCa1 does not exceed 0.0157 Å only for central atom.
The chelating frame O1S1N1P1iO3i is almost flat: the average deviation for all these atoms does not exceed 0.11Å with the maximum deviation recorded for P1i (0.21 Å). In spite of this, the chelated metallo-cycle as a whole has an anomalous configuration: the value of angle between chelate and the plane Ca1O1O3i is 158.5°.
SO2 group implementing the bridge function links the two calciums in a different manner (Scheme 1.).
Moreover, the distance metal-oxygen, implicated in metal-chelate somewhat longer than intermolecular bond Ca - O, which can be explained in the terms of packing effects.
This fact, in turn, did not lead to the noticeable appropriate increase in the length of SO (1.4547 (15) Å) and 1.4603 (14) Å) contacts (as always in the complex under coordination) in the comparison with theoretically identical distances in free noncoordinated ligand (Moroz et al., 2009). Another bite bond lengths and angles around the atoms of phosphorus, nitrogen and sulfur have typical values for the appropriate substituted amidophosphates and sulfamides.
