The new selenite-chlorides with composition Sr{sub 3}(SeO{sub 3}){sub 2}Cl{sub 2} (I) and Sr{sub 2}M(SeO{sub 3}){sub 2}Cl{sub 2} (M=Co, Ni (II and III)) were obtained. They crystallize in monoclinic system I: space group C2/m, a=13.203(2) A, b=5.5355(8) A, c=6.6170(10) A, {beta}=95.89(1){sup o}, Z=2; II Space group P2{sub 1}/n, a=5.3400(10) A, b =6.4279(6) A, c=12.322(1) A, {beta}=92.44(1){sup o}, Z=2; III: space group P2{sub 1}/n, a=5.3254(11) A, b=6.4363(13) A, c=12.197(2), {beta}=92.53(3){sup o}, Z=2. All three compounds are constructed in the same manner. Sr polyhedra form infinite layers, which are interconnected into a 3D framework by means of Sr polyhedra in the case of I or Co and Ni polyhedra in the case of II and III. Se atoms are situated inside the channels of the 3D framework. The topological analysis of ELF for I confirmed that the lone electron pairs of SeO{sub 3} groups are located inside these channels. - Graphical abstract: Three new selenite-chlorides Sr{sub 3}(SeO{sub 3}){sub 2}Cl{sub 2} and Sr{sub 2}M(SeO{sub 3}){sub 2}Cl{sub 2} (M= Co,Ni)
