catena-Poly[[[aqua­copper(II)]-bis­[μ-bis­(3,5-dimethyl-1H-pyrazol-4-yl) selenide-κ2 N 2:N 2′]] dichloride monohydrate]

Abstract

In the title compound, {[Cu(C10H14N4Se)2(H2O)]Cl2·H2O}n, the CuII ion, lying on a twofold rotation axis, has a square-pyramidal geometry constituted by four N atoms of pyrazolyl groups in the basal plane and an apical O atom of a water mol­ecule. A pair of bis­(3,5-dimethyl-1H-pyrazol-4-yl) selenide ligands bridge the Cu centers into a polymeric double-chain extending along [001]. The chloride anions are involved in inter­molecular N—H(...)Cl and O—H(...)Cl hydrogen bonds, which link the chains into a three-dimensional network.

Comment

Study of metal-organic polymers is a well elaborated research area in coordination chemistry. Infinite molecular polymeric arrays are potentially applicable as specifically ordered crystalline substances with reversible selective sorption (Farha et al., 2009; Zhang et al., 2009), electrical conductivity (Zhang et al., 2009) and molecular magnetism functionality (Shibahara et al., 2007).

The title compound was prepared in a water–methanolic medium by mixing solutions of CuCl2.2H2O and the bis(3,5-dimethyl-1H-pyrazolyl)selenide (L) ligand. It is similar to the copper compounds reported recently (Seredyuk et al., 2007, 2009). A square pyramidal environment of the CuII ion is constituted by four non-coplanar N atoms of pyrazolyl rings [the Cu—N distances are 1.988 (2) and 2.017 (2) Å, the Cu—O distance is 2.208 (3) Å]. Adjacent CuII ions are linked by symmetrically equivalent ligands in a double-stranded bridge fashion (Fig. 1). Formed one-dimensional linear chain is running along the c axis, where the Cu atom deviates from the average basal plane by a value of 0.392 (1) Å (Fig. 2). The NH group of a pyrazole ring is involved in hydrogen bonding with chloride anion (Table 1), which further forms hydrogen bonds with both free and coordinated water molecules and additionally with a pyrazole ring of a neighbouring polymeric chain (Table 1). As a result, a dense network of hydrogen bonds is formed.

Experimental

The ligand L was prepared according to a previously reported method (Seredyuk et al., 2007). Copper(II) chloride dihydrate (0.034 g, 0.19 mmol) in water (5 ml) was added to 5 ml of hot methanol solution of L (0.100 g, 0.37 mmol). The solution was left for slow cooling at room temperature. After several days plate-like blue-violet crystals of the title compound suitable for X-ray analysis were isolated. Analysis, calculated for C20H32Cl2CuN8O2Se2: C 33.89, H 4.55, N 15.81%; found: C 33.67, H 4.51, N 15.60%.

Refinement

C- and N-bound H atoms were placed at calculated positions and treated as riding on their parent atoms [C—H = 0.98 Å and Uiso(H) = 1.5Ueq(C); N—H = 0.88 Å and Uiso(H) = 1.2Ueq(N)]. The H atoms of water molecules were located from a difference Fourier map and were refined as riding, with Uiso(H) = 1.5Ueq(O).
