The title compound has been prepared in a similar way as zinc[tris(thiourea)] sulfate. The preparation was carried out in two steps according to following equations:
(1) [ZnCO3][Zn(OH)2] + 2H2SeO4 + 3H2O → 2ZnSeO4.6H2O + CO2
(2) 4ZnSeO4.6H2O + 3 CS(NH2)2 → Zn[CS(NH2)2]3}[SeO4]
5.0 g (0.222 M) of ZnCO3[Zn(OH)2] dissolved in 3.6 g (0.2 M) of distilled H2O reacted with 6.45 g (96%) H2SeO4 (0.0427 M) at room temperature. After the neutralization white suspension was obtained. The suspension into which had been poured 50 ml of distilled H2O was heated at 60°C for 30 minutes. The solution became clearer and its pH=4.
Then, at 50°C was added 10.14 g (0.1332 M) of thiourea. The solution became orange-coloured and under stirring it was kept at 50°C for another 10 minutes. An orange precipitate has developed to which another 100 ml of distilled water was added. The mixture was stirred for another 20 minutes and then cooled down to room temperature. After two days, transparent crystals of length of 0.5 mm appeared at the walls of the beaker while an orange precipitate covered its bottom. Next day the precipitate was filtered off, some orange-tinged crystals have been isolated as seeds that were introduced into the filtrate. After a week clear transparent crystals appeared of the size of 1 cm, of the similar HABITUS as zinc[tris(thiourea)] sulfate (Alex & Phillip, 2001).
All the H atoms were discernible in the difference Fourier map and even could be refined. Nevertheless, their coordinates were constrained in riding motion formalism: The pertinent distances equalled to 0.89Å and Uiso(H)=1.2Ueq(N).
The calorimetric experiments were performed on PerkinElmer DSC 7 and Pyris Diamond differential scanning calorimeters using PYRIS Software (PerkinElmer, 2001), with m = 30 mg, a temperature interval of 93–466 K and scanning rate of 10 K/min. No reproducible DSC anomalies were detected until the symptoms of decomposition at 463 K.

Zinc [tris(thiourea)]sulfate, isomorphous to the title structure, is reported to be a perspective semiorganic non-linear optical material (Ushasree et al., 1998, 2000). It can substitute potassium dihydrogenphosphate in technical applications (Ramabadran et al., 1992; Alex & Phillip, 2001). It has also an exceptionally wide acceptance angle for second harmonic generation (Ramabadran et al., 1992). Its resistance against laser induced damage is good (Venkataramanan et al., 1995).
We have synthesized the title compound since it is expected that it might show similar interesting properties as its known isostructural counterpart (Krupková et al., 2007). As a part of our on-going study of the title compound we report here its structure determination. The investigation od dielectric and optical properties is in progress.
The common features and differences between the hydrogen-bond patterns in both isostructural compounds are shown in Tab. 1. This table shows that the stronger hydrogen bonds are common for both isostructural compounds.
